These Tassel like Flowers will Hang to the Ground and Last for Weeks in Container Gardens

Leave a comment

I have tons of gardening and plant reference books in my home office on tropical plants, succulents, landscape designs, perennials, woody trees and shrubs, vegetables, herbs, fruits, container gardening, and more plant related topics, but I do not have many reference books specifically about annual flowering plants (such as sunflowers, zinnias, or marigolds). I guess that is because my passion with plants started with mostly large showy tropical plants, and annual flowers have always been somewhat of a staple plant to me in Connecticut, thus they are not typically the unusual types of plants I enjoy. I use annuals rarely and only when I want that pop of color in a container combination in the summer. I find annual flowers typically look tired towards the end of summer because they are fast growers and push out lots of flowers, exhausting lots of plant energy, whereas tropical plants and their flowers last well into the autumn season here in Connecticut.

However, I discovered upon researching amaranth annual flowers (herbaceous ornamentals or a short-lived perennial in some climates), a particular species caught my eye last year in a seed catalogue. What I read in one of my books is that they are plants from the “tropics” of the Far East (per the one book I have on annuals, which is an old book!). The book indicates they are “brilliant, heavy-looking plants, reaching 3 to 5 feet tall” and grow in rich or poor soils. Another website indicates they are native to India, Africa, and Peru. In some ways, they are similar to the tropical flowering plants I already enjoy; plants from warmer regions. This is why I picked them as a candidate to sow from seed last year, plus the species I selected is a variety that grows much taller than normal, very tall, reaching 48″ tall. This would be perfect as a specimen plant with my other large showy tropical plants such as canna lilies, elephant ears, castor bean plants, or banana plants in my container gardens and patio pots.

Container Gardens by Cathy Testa of Container Crazy CT – Featuring Amaranthus caudatus

Coral Fountain Amaranth (Amaranthus caudatus)
Love-Lies-Bleeding, Amaranth, or Tassel Flower

Of all the common names or flower descriptions of this plant, I guess tassel flower represents the flower form the best in my opinion of this species I selected. The plant’s large plumes (technically called inflorescences) dangle down in clusters of coral colored tassels as if they are fastened at the top of tall stalks. The flowers are fuzzy, clumpy, and resemble dreadlocks (another great word to describe their form and appearance!) They are chunky and petal-less. They resemble fountains or waterfalls in form, and may be used in wedding bouquets, as cut flowers in vases (long-lasting), and in container gardens where you wish to present a dramatic unexpected showy element. The foliage is not very large, and are a lime green lighter color on this type of amaranth, and I read the leaves are edible, but I did not experiment with that aspect, yet. After admiring the interesting aspects of this flowering annual with cool attributes, I decided to sow some seeds last year and give them a try.

Coral Fountain Amaranth – Cascading Plumes

When to Sow the Seeds

The seeds should be started indoors either at the end of March of middle of April based on our weeks before our typical spring frost timing in Connecticut (or use the appropriate 4-6 weeks before your last frost of your planting area). You may also direct sow these seeds in the ground after the threat of frost has passed (frost threat ends mid-May usually in Connecticut – check your weather and seed sowing charts). The seeds take 75 days (or about 2.5 months) from the time you transplant them to produce flowers. Starting them earlier will give you more time to enjoy the flowers which last well into the end of summer. The seeds are tiny and the packet has up to 250 seeds. That’s a lot of amaranth sowing, so use caution when sowing to not over do it.

Seeds Sown in a Flat Tray

Some Sowing Problems I Experienced

However, I experienced some problems when I sowed them. I did a whole flat tray of them, and they seemed to not be really pushing growth a while after germinating, so I painstakingly put them in 2″ round mini pots one by one and thought I’d wait to see if that would help. It did, but one day I left the tray of the mini pots outside by my greenhouse and a rain gutter above rushed water down on them during a rain fall that day – pretty much destroying them all. All the tiny seedlings got stressed and the potting soil completed washed out. My bad – I’ll remember there is a gutter above problem next time, but I did manage to salvage a few seedlings and decided to put them in planters later when they were large enough to transplant after all chances of frost. I think the reason they may have been slow to grow from seed initially is because seeds germinate best at 75-80 degrees F and they need a night temperature of at least 65 degrees F after transplanting. Maybe my night temps at the time in my greenhouse were not warm enough but I am not sure.

ACK! Rain gutters heavy downpour washed out all the soil

Exposure Full Sun or Some Shade

One of the containers I planted them in is a rather large round black container in my back yard (probably at least 3 feet in diameter and about 4 feet tall). I put canna lily plants, elephant ears plants, and some of the amaranth transplants I managed to salvage in it. The seed packet indicated the plants like dry, hot conditions in full sun but will grow in partially shaded areas. The large black round pot is on the east side and gets shade part of the day. The packet also indicates the plants are drought tolerant (and may get root rot in poorly drained soils where is stays wet in the ground all the time, which was not a concern for me since I do all in patio pots and container gardens with sufficient drain holes). A drought tolerant plant is beneficial for container gardening, however, as you don’t have to worry about dragging the watering hose or watering can out there too often in the summer to water it. They are very easy to grow and tolerate poor conditions once the plants start to grow and get established, in fact, you may want to use caution with not overwatering it once it is doing well. Wet soils for this plant may lead to root rot per various sources.

Use Large Pot Sizes and Sturdy Stakes

Because this species of amaranth grows very large and tall, place this plant in an area where you enjoy witnessing them cascading at the corners or edges of your patio pots. Consider taller upright planters because of how the plumes will descend down in big chunks towards the ground level. You want to be able to enjoy how they flow downwards like a waterfall without them hitting the ground. Fortunately, that was the case of my big round black pot in the backyard. As I started to see them progress, I thought about the wild and unusual form being a real show stopper if they were staggered in huge garden. The plums grow so long and become top heavy thus a good support stake is recommended when they start growing flowers. I used thinner bamboo poles which would be hidden against the stalks in the pot. The weight of the flower plumes becomes substantial as they start to grow well and large into the summer months.

Companions with Darker Foliage

Consider pairing it up with plants with darker foliage and use tall plants too. The color of this amaranth’s leaves are a light lime green with an oval shape, and the flowers are a light coral color. It will show up more against a darker foliage plant, like a canna lily with plum colored foliage or a castor bean plant with the darker foliage. And consider pairing them up with other plants which are mid summer bloomers so you will get a mix of bloom colors for the look you wish to achieve in your patio pot or container gardens. I noticed hot pinks looked great with them too for contrast. Think hot pink canna lilies.

Used in Floral Arrangements for Weddings

I started to create a board on Pinterest last season to show what the flowers would look like, but this board is of other photos of various Amaranth plants. I discovered quite a few photos where the flowers are used in wedding bouquets and arrangements, but the only consideration I had on that is when the flowers reach maturity, they tend to drop tons of tiny little seeds. When I placed some in vases last year, it dropped lots of seeds on my outdoor patio table. I wondered how they work with those as cut flowers for floral arranging to avoid that problem (the potential mess it makes), and realized that would take some more research. I now realize you would have to harvest the flower tassels before they mature to avoid the abundant seeds in them later. The flowers plumes bloom from July to frost, and mine were full with flower plumes towards the end of the summer here in Connecticut. If you wanted to grow some for a wedding, you would want the wedding to be a summer wedding and again, harvest them before maturity so you don’t get a situation of tiny black pepper sized looking seeds falling down your wedding aisle runner. The plumes also look great in tall vases and provide a rather exotic interesting vibe in outdoor spaces. They may be used as fresh flowers or in dried flower arrangements. In fact, I saw some in a floral shop this winter and I kicked myself for not saving the plumes of my own last summer.

Bees Loved – Many Visited!

Food for You or Pollinators

Some reference books indicate they are favored by bees and that is true, I did see lots of bees visiting the tassels of its petal less flowers and took photos, and at times I would witness a bird perch on the tall thick stalks. Additionally, there is some information about how parts of the plant are edible and seeds may be used in porridge. I didn’t really look into that much however. Maybe this year when I grow them again, I will do so. The seed packet indicates amaranth are one of the most nutritious of the ancient grains. This turned out to be a stunning plant, which friends and family noticed, when they visited. I had one by my entrance stairs, and one day, my brother shouted out as he was leaving, “That plant is cool!”

Amaranthus definitely have a cool vibe!

Great Plant for our Important Bee Pollinators

A Smaller Rose Perfect for Patio Pots and Container Gardens

Leave a comment

When I worked at a garden center years ago, they had Knock Out Roses always in stock for sale. I recall Knock Outs were easy care, disease resistant, and great repeat bloomers, but for some reason, I can not remember exactly what made them special, other than they were really reliable compared to other fancier roses. I’d walk around looking at them at the nursery outdoors, leaning down to read the tags and smell the blooms, and always admired them, but I had never seen a compact variety of Knock Outs Roses until last year.

Photo 1 – Upon Planting Memorial Day Weekend – Knock Out Rose Petite with other plants

That was when I spotted the new member of the Knock Out family – last summer at a local nursery. Because I was familiar with the Knock Out logo and pots (from years ago), it caught my eye right away from a distance, and I thought, “Is that a miniature or smaller rose by Knock Out?” Long story short, I grabbed a few because the smaller new size, called Petite! Knock Out, is well suited for patio pots and container gardens for our summers here in Connecticut. I also knew that my customers would like traditional rose blooms in their outdoor planters. It would be a nice addition to the urban outdoor setting with various planters throughout the area.

Photo 2 – A Month or so Later after Planting It

The Petite Knock Out rose color is a beautiful intense deep red (their website refers to it a “fire-engine red”), and the plant’s tag indicates its mature size would be about 18″ tall, and that really is perfect for patio pots and containers, plus roses are sun lovers. These required about 6-8 hours of full sun and my customer’s site is definitely a sunny location. Another aspect is these are easy to carry to my location and plant, which is a side bonus for me as a container garden installer. And it would bloom all summer into fall (long-bloomer candidate!). What’s not to love?!

Photo 3 – Later in the Summer towards fall season – by Cathy Testa of Container Crazy CT

I usually don’t plant or play with roses too much. Some will say roses are for experts and/or I know roses may develop issues, insects, or diseases but the thought of using a smaller, more compact, or miniature rose from Knock Out didn’t scare me. As I took photos at different times, it is apparent the blooming power of this Petite Knock Out Rose plant did not disappoint. Looking at the sequence of the above photos, you can see Photo 1 – upon planting, it has many buds ready to open, Photo 2, lots more flowers opened a month later, and Photo 3 was taken at the end of the container gardening season, towards the start of fall. The flowers are still abundant right before our fall season. And the blooms retained their deep fire-engine red color. When you have very full sun situations, as in super full sun, sometimes flower colors will fade, but they did not fade on this Knock Out Petite. Take a look at the foliage as well – shiny, healthy, and no issues. No signs of trouble, thus, I and my customers’ were pleased.

Plectranthus – Flowing Over the Planter!

The Knock Out Petite retained its shape overall, did not overgrow the tall blue planter, but the trailing spiller plant next to it got rather large. Sometimes I laugh at myself, when I see how big a plant got over the course of the summer, and I have to always remind myself to restrain my plant enthusiasm and remember that some plants will grow faster and fuller than others. So next time, a more controlled spiller perhaps with this rose plant will be used.

Early in Season – Container Gardens By Cathy Testa

This Petite Knock Out Rose will give a show from the time you plant it till end of the container gardening season in Connecticut, then you may transplant it later if you wish or store the container with the rose shrub in it in your garage or basement over the winter. After my first year of using the new Petite Knock Out rose, I can’t think of any flaws with it – so it is a nice one to add to your full sun locations list. Well, one flaw, make more of these with other bloom colors. Again, it is noted as disease resistant, but that doesn’t mean it can’t get diseases. Overall, I find if you select a healthy plant to start and maintain your container gardens with appropriate watering and care, all should move along well. Container gardening is not like that of a shrub in the ground which may get subjected over the long term to issues, but anyhow, I really was happy to find a smaller rose plant perfect for container gardens and patio pots.

Container Gardens by Cathy Testa of Container Crazy CT

Plants in this tall blue planter are: Petite Knock Out Rose, Delosperma ‘Pumpkin Perfection’ (orange flowers; called Ice Plant), Senecio (succulent plant with blue foliage; called Chopsticks), and Plectranthus (white edges to leaves and a spiller habit). As far as planting requirements, full sun, potting mix for pots (I added a small amount of aged compost), and use at least a 12″-14″ diameter pot for this size plant, but in my case, I used a larger and taller pot. Go with about 16″ deep, but deeper will help those roots grow down, and use larger pots if adding more plant candidates with the rose. And oh, placement: I suggest you put the outdoor planter near a window if you are able to do so, it will allow you to see the roses from the inside too.

For a Wall of Flowers, Use Mandevilla Tropical Plants in Container Gardens

Leave a comment

Mandevillas are amazing flowering tropical plants for full sun locations in the summer in container gardens and planters, and I always enjoyed looking at them, but for some reason, I didn’t plant them very much at my own home location, until a couple years ago, when a clients’ needs to cover a wall with flowers lead me to paying attention more to mandevillas.

Perfect for walls, trellises, arbors and more…

If you have an area to grow a beautiful flowering plant upwards, such as a wall, trellis, lamp post, arbor, stair railing, fence, mailbox, or in a pot with a support trellis, these plants are perfect candidates. In Connecticut, mandevillas will bloom profusely on upward growing vines with big dark greens leaves when provided enough sun and heat, and appropriate growing conditions. They work very well in containers, planters, patio pots, and don’t even require super huge pots to thrive.

Mandevilla at a Client’s Home

Above is an example of a wall located below an upper deck. The white blooming mandevilla vines were very lush and full, growing from a planter about 24″ diameter and just as deep. It was facing the sun most of the day, and it looked absolutely fabulous, reaching the top of their deck that year. These plants will twine fairly quickly onto supports with many funnel formed flowers opening over the course of the summer to fall season in Connecticut. They must be taken in before fall frosts or overwintered immediately after being touched by frost. See my “Overwintering” posts for more information on that aspect.

Cathy Testa with two Mandevillas at her home in Broad Brook

In the next photo, here I am in between two plants in blue pots at my home. The base plants (serving as fillers) are Tradescantia pallida ‘Purple Queen’ (annuals in CT). I put really tall trellises in each pot along this wrought iron fence, which is on the driveway where the plants got full sun all day and my watering hose was easily accessed. You will see they were growing taller than me and if the trellises were higher, they would keep growing up and up and up.

In a Pot Growing Up a Staircase Railing

And I wanted to grow one up my stair case railing to reach the overhead arch, it almost made it to the top. It helps to use garden twine to guide it along and give the vines something to reach and attach to as it twines up. The purple pot below used for it is probably about 2 feet deep, but you may grow these plants in even smaller pots. More on that later.

Side View on the Driveway
Cathy Testa standing in front of a Wall Planted with Mandevilla Plants

And here is a photo of me with the mask on, primarily because I wanted to show the timing of this photo, of a wall I just planted. It wouldn’t be long for the plants to produce more blooms. It does help if you start with taller plants if you are looking to gain the affect of covering up something like the wall in this city photo. They will grow as high as the support system they can attach to. If I had a higher wall here, it would keep growing up all summer. They don’t grow as fast as morning glories, as an example. The growing pace is moderate, so if you want to get one to really show off, get the taller specimens to start with. They may be a pricy but so worth the display and enjoyment you will get by using one or more in your outdoors spaces.

Stunning Against Blue Skies!

Moderate climbers that keep on growing up…

Mandevilla vines will reach to the heavens, if you allow them to – they seem to never stop wanting to reach up into the skies. If you are able to acquire taller specimens to begin with, it is worth it in my book. They come in white, pinks, and reds for bloom colors. I haven’t grown the red ones yet, maybe this year will be the year.

Inspecting the leaves

Some of the varieties have glossier leaves than others. The leaves on the white blooming one, in my photos, were about 4-6″ long. A good tip is to inspect the foliage when you are looking for one during out Connecticut container gardening growing season, and although you might experienced a stressed leaf or two based on when they arrived in Connecticut (cause most of them are shipped here from warmer states), they usually bounce back quickly when potted up and provided the right soil environment and sunny conditions in your planters. It is not to say they don’t suffer some minor issues, but a good tip, again, is to inspect your plants. See a healthy tall one – don’t hesitate to grab it.

Now that is a HEALTHY A** LEAF!

Sometimes I admire foliage of plants more than flowers, especially when they look almost perfect. Not always achievable because we are not plant Gods, but the leaves on this plant that year, wow, so shiny and healthy. To achieve good results, be sure to have well draining soil, use pots with drain holes (see my 5-Must Do’s for Container Gardening), and inspect the plant from time to time. Sometimes, during inspections, I may discover nice insect visitors, like bees, lady bugs, butterflies, and moths.

Not damaged by serious pests, but bothered if conditions are not right…

So far, I have not encountered serious pest (bag bug) problems on mandevilla plants, but I do think they don’t like “inappropriate environmental stress” and things like too cold of temps, or too much wind, or neglect from not watering regularly. Those aspects will weaken them, and you should also avoid areas with high salt (maybe road side). Do not plant them in containers or your patio pots in Connecticut outdoors till well after all chances of spring frosts. So, you would plant them around the same time as you put out your warm season vegetables, like tomato plants.

Heat, sun, and well-draining soils…

The plants want heat and sun, well-draining soils, and appropriate watering. These are tropical vining plants and they don’t like the cold, so remember that on your timing in spring time. They want warmer temps at night so even if the an early spring day feels okay, the cold temps at night are not good for them in early spring before frosts. Also, for more blooms, get some bloom booster liquid or water soluble fertilizer and fertilize a couple times a month in the summer after the plants are established if you feel there are not enough blooms being produced on your plant. It is a good idea, like most tropical plants or plants indoors over the winter, to acclimate them to outdoor summer conditions.

Acclimating a Stock on My Driveway
The In and Out Year

One year, I had to pick up my mandevillas orders earlier than normal, so I literally moved them in and out of my greenhouse during the later part of April into mid-May before planting them at a location. I didn’t want to subject the plants to cold temperatures of the evenings, but I also wanted to give them natural sunlight during the days (on good early spring days). It was a “Mandevilla Workout!” As noted above, do not plant them until around Memorial Day in our area of Connecticut (Zone 6b). They are from areas of warmth, sunshine, and moisture – so remember these 3 environmental conditions for your mandevilla plants. If temperatures drop or if you put them out too early, your plant will experience stress, leaf drop, and potential diseases later, so be sure to protect them from the cold in early spring before frosts if you pick any up early in the container gardening season in Connecticut. An occasional drop in temps in the summer is fine however if we get some freak cold (like we did last year in 2021 on Memorial Day weekend!), they should bounce back from the heat of summer, which mine did that year.

Pretty with the Ornamental Grass nearby

Of course, you may plant them into the ground but I typically do not do that. In this photo above, the pink mandevilla is in a pot below my driveway climbing up and an ornamental grass is in the background, which I thought looked lovely together as a combination.

Cathy Testa of Container Crazy CT

As you can see, mandevillas make me happy. I love planting them and watching them grow all summer long. They turned into a plant I barely gave a second glance to, to one I can’t stop admiring now. I hope you will admire them too.

Pots don’t have to be really big…

And I noted you really don’t need big pots. Sources will say keeping them in smaller pots will force the plant into growing the top part of the plant more rather than focusing on growing roots for Mandevilla. In my experiences, I’ve done both, repotting into a 22″-24″ diameter planter or inserted the nursery pots into a larger planter, but be sure to allow draining in either scenario from the base of the pots. And the soil is best on a organic side. I have amended the soil with aged compost in pots with potting mix. I tend to space them right next to each other when creating walls in big planters. However, in gardens, it is recommended to space them apart by 8″. Probably the best maintenance tip is to water them regularly and not let them dry out too much. They have thick chunky root systems, so if the pots is smaller, you may see the nursery growing pot expand as the roots are trying to move around, pushing against the sides. In those cases, I’ve used a razor knife to cut the pot off the root base before planting them.

Trailing Red Small Daisy Flowers that can Take it Rough

2 Comments

I am always in search of tough (as in tolerant) plants for container gardens and patio pots for full sun locations due to having a few clients with these environmental conditions at their outdoor settings. In fact, I often refer to the location as “full on sun” when I talk to my husband about it, and he jokes about that term to this day. It is a hot location with lots of heat in the midst of summer with limited water sources outdoors. Thus, I like plants to be drought tolerant if possible.

Last year, I happen to notice an annual plant at a local nursery with light green and white succulent like foliage, and thought this may be a candidate for my full sun project because the succulent foliage led me to believe it probably is similar to a succulent plants (able to retain water in its leaves and are drought tolerant) but I wasn’t sure.

However, despite not knowing the plant’s requirements as of yet, I also noticed it blooms small red flowers and I was in search a red and yellow combinations for a theme I was planning on this site that year. I looked at the label, of course, and thought it over and decided to give this annual plant a try.

‘Mezoo Trailing Red’ is the Tradename

A Spiller in Habit

In addition to having the succulent like foliage, the hot red colored blooms are what I was searching for, and having a bit of an unusual variegated foliage coloring, it also would work as a spiller plant (plants which trail or hang down in planters and pots). I grabbed a couple to add to my selections to plant in some large long planters. And, also, it has a lighter tone of a foliage color, making good contrast to darker plants.

‘Mezoo Trailing Red’

It is known as ‘Mezoo Trailing Red’ as the tradename, but upon some research, I discovered it’s botanical name is, Dorotheanthus bellidiformis. Try pronouncing that one! So, I will just refer to it as “trailing red” or “Mezoo” in this post. It is a tender perennial that is winter hardy to planting zones 9-10, but here in Connecticut, it is treated as a annual plant and is not hardy in our CT zones. I’m in Zone 6b.

Easy to Root

However, I discovered yet another benefit about this plant, it is easy to root from a tip cutting by placing it in a jar of water and letting roots form from the stem end tip. I did that after the summer with some cuttings and managed to start a couple smaller plant to keep in the house over the winter.

Great with Darker Contrasts nearby (dark greens), and also looks nice with soft blues!

Blue Green Coloring

There are different types of green and the foliage green on ‘trailing red’ is a bit of a blue green with hues of white to creamy white edges on the leaves. I thought how it seemed to click in color with a few blue Senecio plants I had to plant as well, which I used a little fillers to tuck in next to the Mezoo trailing red plant. However, by the end of the summer, Mezoo took over the area in the center of this tall and long planter. The Senecio got crowded out quickly. I didn’t mind, however, because Mezoo turned out to be just beautiful and full to the max.

Abundant Growth

The amount of growth that occurred in one summer in the planters really shocked me when I returned later in the season to take a look at the plants. The Mezoo was lush, full, and trailing over the edge down to the middle of a 5-6 foot tall square planter. There were no signs of insects and about the only issue I had with it was as some of the leaves dried up here and there (just a bit), the dried up papery residue of the leaves stuck to the outside of the planter under the plant’s hanging foliage and blooms. I washed that up later off the planter, when I took the Mezoo out of the planter, before fall arrived, by using some mild soapy dish type water. I was glad the planter’s outside covering was not damaged.

Drought Tolerant

This is the type of plant that tolerates some dry periods as well, which is a bonus. It is low maintenance and takes somewhat dry to medium moisture. Well-drained soil is preferred by it, and I had placed between two dark green globe shaped shrubs and thus, the plant was somewhat protected, but I don’t think it needed any extra protection. It grew massive and was impressive. It dripped over both sides of the planter, to about half-way down. I was impressed. Take note, it doesn’t like to stay completely dry and fortunately, we had good rainfall to get some moisture into the soil in the planter that year.

Overflowing Abundance

Like a Waterfall

Just look at this photo above. It is very apparent this plant was thriving. It was full, lush, bursting with foliage and flowing thru the two side shrubs like a waterfall. When I saw this abundance of growth, I said an, “Oooohh, so nice!” comment out loud to myself, which is typical of me. I surprise myself sometimes. LOL. I was pleased.

When I got back to my greenhouse, from digging it out at the site, I decided to take a few cuttings (as noted above) and showed it to my plant followers, and immediately a friend and plant enthusiast chimed in to say she has one as well and loves how well it performs in her hanging baskets at home. She also takes tip cuttings to root as a method to save some over the winter months here in Connecticut.

Sometimes its worth a shot to try out a plant you are unfamiliar with and often they will give you clues to their habit and tolerance. This one I would definitely recommend for sunny locations in containers and patio pots. It handled the heat, wind, sun, limited watering, and crowding between two other plants pretty well. It has a lower habit (doesn’t grow upwards), so if you don’t want to block the view behind it, which we didn’t want to block the skyline, it worked very well and I experienced no insect issues on it all summer long. I will say, we did have more moisture than usual that summer and maybe that helped, but overall, it can take it rough.

Blooms are Small but Long Lasting

It also blooms many daisy red small flowers from about June up to October. The flowers do not fall off so no worries about a mess on the ground area and also no worries about deadheading. I do wish the flowers were larger however.

Later in the autumn season, I ended up tucking some of those cuttings I took on top of my succulent topped pumpkin centerpieces. I guess the bonus list continued onward. It just hit me how they would look pretty on my pumpkins.

Hot Pinks for Full Sun in Containers

Leave a comment

Here’s a combination I created last summer for a client. I loved the way these plants thrived. Despite some troubling weather set-backs we had in 2021 at the start of the container season, they performed beautifully all summer into early fall. These plants tolerate full sun, drought, and wind fairly well.

Hot Pinks For Full Sun – Upon Planting Photo of Dipladenia, Calibrachoa, and Sedum stonecrop

The beautiful fluted hot pink flowers of the tropical plant in the center, called Dipladenia vine, was a perfect candidate. These plants continuously bloom and hold on to their blooms pretty well in windy conditions. It does not vine upwards, like Mandevilla vines do, but spread out more as it grows. The flowers are just gorgeous, and sometimes towards the end of the summer, they may fade a bit to a softer pink but overall they retain their form and color beautifully in containers.

Paired with Calibrachoa (left lower plant) – An annual in CT

I paired up the Dipladenia (thriller plant in the center) with a annual plant, Calibrachoa. The Calibrachoa has small Petunia like blooms on trailing stems which would eventually cascade over the rim of the pot (serving as a spiller) in this combination. It also is a sun lover and prefers well-drained soil kept evenly moist. The reason I selected the Calibrachoa, an annual plant here in Connecticut, is because of the coloring and form of the flowers. It has an outer pink to lavender color with a ring of a darker toned pink in the centers of its blooms. It was one color I had not see before for this annual, and thought of how well it would pair with the hot pink Dipladenia. It repeats the form of the larger hot pink flowers of the Dipladenia, and shares the same coloring in the pink hues.

Calibrachoa spilled over the edges

Also tucked in the corner is a Sedum (stonecrop) (see top photo on right) which is a perennial. It is called ‘Firecracker’ of the Sunsparkler series. Again, using another sun lover which tolerates periods of drought. The Sedum is hardy in Connecticut as a zone 4-9 plant, and blooms from late summer into early fall, however, it ended up getting hidden by the plants next to it by the end of the season. You couldn’t see it later in the season which is unfortunate, because I loved how the burgundy shiny succulent foliage gave a darker contrasting color to the hot and soft pinks in the combination. Sedum stonecrop plants makes nice groundcover in hot full sun landscapes, and again, I tend to use perennials in pots here and there as the anchors or foliage (filler) plants. They are good performers and easy care plants in either situation.

Full by mid-Summer into Fall

To the right of the planter with the hot pinks, I planted a large leaved perennial, a Lamb’s Ears perennial plant with a hardiness up to Zone 4. It is a hardy plant in Connecticut, typically used in sunny landscape beds, but I enjoy using perennials in my container gardens as well for adding the foliage power. I knew the soft, silvery, woolly leaves would look beautiful with the hot and soft pinks nearby. These plants are very easy care and again, love the hot sun, and can take drought. This Lamb’s Ears is called ‘Big Ears’ (Stachyz byzantina) because the leaves are huge, and the plant caught my attention right away. Bigger than the typical varieties of this plant, it was a perfect candidate for the tall planters. Another benefit of this plant is it is not preferred by deer, which is not an concern at this location but good to know for use in landscape beds. I also find, if planted in full sun, it doesn’t get any insect issues. If you try to plant it in shade or part sun, it won’t perform as well, and may even rot if in a damp location. And of course, it is soft and fluffy, and one of those plants you like to touch which makes it a fun candidate in outdoor areas on patios, decks, and wherever you may reach out to touch it. It grew at least two times bigger by the end of the summer season in its planter.

Stachys byzantina ‘Big Ears’ (Perennial, Hot Full Sun, Zone 4 Plant)
Evolvulus pilosus ‘Blue Daze’ annual

In the smallest of the trio of tall planters, I planted a plant with soft blue flowers which are also sun lovers, or part sun. These bloom all season and tolerated the conditions at this site well (hot sun, windy, periods of drought). However, by the end of the year, while the plant grew huge, it didn’t have as many flowers as I expected, but the foliage stayed lovely. I had written about this plant before. I used it in wedding container gardens for a client. Blues is a tough color to find in blooms and thus, this is one of the blues available. It doesn’t drop its flowers nor require deadheading, which was a bonus. And no insect issues encountered. I only wished it was more prolific with blooms. I loved the way it looked with the other two planters, soft delicate foliage, and easy care. And as noted in my prior blog post about using these years ago, I learned the blooms close during cloudy conditions and or in the evenings, as you can see in this photo below.

Late Summer

But what you may also see is all the plants were extremely full, lush, and healthy all the way into early fall as shown in the photo above. You can even see a bloom that formed on the Lamb’s Ears on the far right. It was a shame to take all the plants out when I replanted for the fall season, but at the same time, it was a pleasure to know this combination performed well. The perennials may be salvaged at the end of the season by replanting them in your landscape beds. See more photos below. And, thank you for visiting my blog!

Flowering Tropical Plants for Decks in Connecticut

Leave a comment

Are you new to Connecticut and have no idea what flowering plants you should grow in containers or patio pots on your deck this summer?

I saw this question asked by a CT newbie on a gardening group on Facebook recently, and thought, hmmm, that is a GREAT question.

So to start to answer the question above, I will share some of my suggestions. Let’s start with tropical plants:

Flowering Tropical Plants

If you are new to Connecticut, you may not be aware of the wonderful tropical style plants which showcase beautiful flowers and are perfect to grow in container gardens and patio pots on your deck this summer. The key thing to know about tropical plants is that you should not put them outdoors until after frost in the spring here in CT (known as the last frost date) because tropical plants can not tolerate frost conditions. Thus, the key timing is to put them out around Memorial Day as a guide. Frost usually occurs around mid-May and it changes slightly year to year but mid-May is a good all around watching point, check the weather forecasts, etc. Once we are past frost, many tropical plants do wonderfully during our summers here in Connecticut in pots, planters, and container gardens.

Blooms all summer

Another cool thing about using tropical plants is many tend to bloom all summer into the fall season, usually into September and October, without fading or wearing out as with other annuals type plants. They usually showcase long lasting flowers. And just as with spring timing, you have to take them in before the frost which occurs in the fall in Connecticut. I blog a lot about storing underground tubers, rhizomes, corms, etc. here on this site which you may search for in the fall on this blog by using the search word “overwintering” for more details on when you should take them in and steps to store them over the winter to reuse each season.

Hot Pink Canna Lily Flowers

Canna Lily Plants

Canna lily plants are not hardy in Connecticut, at least they used to not be hardy, but if grown in the ground, they sometimes come back (due to global warming). That’s another story, as the focus of my blog site and this post is about growing them in pots.

In pots, you may plant them using plants you would pick up from a local nursery (or from me if local to my area – see below). Or you may start them by purchasing the rhizomes and planting them in one gallon size nursery pots indoors with potting mix to give them an early start, in March. They will start to grow from the rhizomes inside the house, and then you may transplant them outdoors after our spring frost in Connecticut by the end of May typically.

Love full sun, grow really tall, not a lot of problems

Canna lily plants love full sun but they are also okay in part sun or even part-shade. Many grow really tall and others species or cultivars are dwarf sized. Anywhere from 4 feet to 8 feet or taller. Their flowers attract hummingbirds and the plants are easy care. Flowers are pink, red, yellows, peach, orange, and some have dark burgundy colored leaves.

Speckled with red on yellow flowers

I usually do not encounter insect problems with Canna lily plants, other than the Japanese beetles that come out one time a year in the summer, they may eat some of the leaves and you may see some holes, but the beetles don’t stay out all summer so I usually just cut the damaged leaves off and tolerate them for a month. This occurs in July or August on one or two plants. Sometimes they only bother one of my plants and leave the rest alone, so I don’t find them to be a nuisance.

How to plant them…

As far as planting them, use a good quality potting mix and add some compost. I typically add slow-release fertilizer to all my container gardens and patio pots as well. See my prior blog post, called the 5-Must Do’s for more information. I typically don’t regularly fertilize my Canna lily plantings on a monthly schedule, with liquid plant food as often recommended, unless I have the watering can with me and I’m fertilizing other plants, than maybe. But, in general, they are very easy to grow. They tend to be low-maintenance plants, other than the part about storing them over the winter, that is a bit of maintenance in the autumn season, but worth it if you wish to reuse them each season. And of course, as with all container gardens and patio pots, you must water them in the summer as needed.

Very Tall Canna (dark foliage) in a large square planter on my deck 2020

Can be top heavy…

One thing to note about Canna lily plants is that they do grow tall and their stems are usually thick enough to stand on their own, so staking is not required at all, but I typically grow them in large pots of 22″ in diameter at a minimum and about as deep. They tend to multiply and produce more shoots so a good clump can form over the summer. As a bigger clump of stems form, it can be top heavy in a pot, and if a small pot is used, they may toppled over from the wind at times. The rhizomes from which they grow are usually about 6 inches deep in the soil, so when you are ready to take them out by digging up the tubers in the autumn season, you will find them there in the soil below. And if you are growing a really tall variety, be aware a very windy location could tilt them, but I don’t encounter that here at my house on the deck. I’m talking if you grew them on a high rise or place where it is unprotected with super strong winds.

These toppled over from wind at times last year (pot was really not stable enough for the tall varieties)

Make More Plants!

Another great benefit to using Canna Lily plants is they tend to grow bigger rhizomes each season. You may dig up the rhizomes in the autumn season, and divide them into pieces and store them from late fall and over the winter in a cool basement, dark place, and where it will not freeze (where it will not drop below 32 degrees F). You get more plants over time with this process.

Thriller in Arrangements

As I’ve noted before, a good balance of plants in container gardens is having a thriller (tall center plant), spiller (drapes over the edges of pots and hangs down), and fillers (self-explanatory). Canna lily plants make excellent thrillers. They give height to your container and planters, and bloom all summer into fall, non stop. As flowers fade, just remove them if you wish, keep the plant cleaned up as desired, and enjoy them all summer on your deck. And best of all is seeing hummingbirds zoom up to the flowers while you sit and enjoy their show.

Pair Them Up With..

Practically anything. As you see in the photo above, I have succulents in the base of the planter with those tall Canna lilies and various annuals. They are great with practically any warm season loving plants that enjoy full to part sun. On this post, about my Aqua Blue Planter on my deck from 2020, you will see a list of the plants I used as fillers and spillers below the tall Canna lilies. Many larger leaved foliage type plants do well with Canna lilies as well, such as Elephant’s Ear (Colocasia), which are also tropical plants. They do flower but usually only one or two blooms. However, for a tropical look, I just love using the big ears of Colocasias with my Canna Lily plants and other topical plants with fantastic foliage. Because many succulents enjoy summer hot weather, they pair well as fillers too.

I will continue blog about other tropical plants great on decks in the summer in Connecticut.

Tomato Seed Sowing and Planning

Leave a comment
Tomato Plants 2021
Tomato Pots Deck 2021

These photos motivate me to sow and grow again in 2022. I know we experienced some rough wet summer weather (as noted in my prior post) last year, but photos are what prompt me to grow again. Let’s hope we have a good growing season this year!

Goldie Tomato – an Heirloom

Nothing pleases me more than when a person who purchased a starter plant from me sends or texts me a photo as they start their harvest, such as in this photo above, sent by Shannon. Doesn’t that plate of fresh Goldie tomatoes make your mouth water?! I am planning to grow these golden delicious heirlooms again in 2022.

I also add a new tomato or two to my sowing and growing list for each season and will be providing that list to my regulars or post it on www.WorkshopsCT.com soon.

Paul Robeson Tomato – 2021

This photo of a tomato, with a bit of a purple hue, sliced up on a white plate was taken by me last summer. It is the Paul Robeson tomato with orange, green, and purple hues. It produces large sized fruit and the fruit resists cracking. I plan to sow some of these seeds as well this year. Another keeper on my list. And I pray for better weather so I can eat more of these this summer!

Basil 2021

An an absolute must to repeat sowing again are the basils. OMG, how can one have a fresh home-grown tomato sliced up on a plate without fresh basil leaves? I can smell it now – almost!

So in January, as I write this, on 1/13/2022, I have decided on which I will sow again and have ordered my new varieties for sowing. Check! Seed ordering done!

Frost on Plants

Leave a comment

It finally arrived here in Connecticut. Frost on our plants. Last week, it dropped into the 28 degrees F range in the evenings of Friday and Saturday (Nov 5-6th weekend).

For months, I was putting away frost tender plants from my container gardens, because I wanted a head start and it takes a lot of time to dig up plants from pots to store underground portions (rhizomes, corms, bulbs) for frost tender plants, as well as move containers into my garage or basement for the winter months, or just doing cleaning of empty nursery pots for use next season.

The frost of fall appeared a bit later than last year in 2020 (it was on Halloween weekend in 2020), but this year, in 2021, it decided to arrive about a week later, and we could feel it. As I walked out of my house the other day to check my greenhouse to make sure the heat was working well, I saw frost on my truck.

Frost 2021 Nov 5-6 weekend

I carefully walked on the frost covered grass and carried my flashlight to point here and there, hoping I wouldn’t stumble upon any wild animals, on my way over and down to my greenhouse. It is kind of pretty to go out at an early hour, think it was like 5 am, and see all the glitter on the plants outside from the overnight frost. But it was very cold and I didn’t stay out there too long in my slippers and PJ’s with a very thick bathrobe!

Later, when the sun was finally up, I got a glimpse of a rose bush near my house and I thought, look how pretty that is with the glittering frost on the roses!

While it may look pretty on the outdoor plants, we definitely do not like seeing our tropical plant toppled from frost, which is why I did all my overwintering chores early. It seemed to take forever. My list pretty much consists of Canna Lily plants, elephant ears (Alocasia and Colocasia), red banana plant (Ensete), some Mandevillas, and of course, I move in all my succulent and cacti plants early as well.

This year, I made a note on my calendar to check my stored tubers, rhizomes, corms in about a month. I want to make sure there is no rotting or problems. Last year, I ran into that and I think it was due to not having some air holes in new plastic storage bins I used, so I drilled very small holes into the covers of my storage bins which are kept in my unheated basement, stacked up in a corner, where it stays cold but not below freezing during the winter months.

And as I noted above, I check my greenhouse in the early part of the winter heating phases to make sure all is going well, that the heat is on, and I will sometimes take the flashlight and look at the plants. Did you know, some critters (insects) come out at night. Not common in the winter months cause the greenhouse is kept at a low temp (around 50 degrees F), just warm enough to allow my low temp tolerant plants hang in through the winter months.

In the winter, I pray for sun during the day hours. Not only for myself but for my plants in the greenhouse, so they may stay toasty warm during the winter days (and not utilize any heat). The cost to heat it is getting a bit too much. But so does a good dinner out! LOL. Choices!

My greenhouse also doubles as a creative space for me to make items with plants for the decorating seasons, such as upcoming holidays. It can be cool in there in the midst of winter however, requiring me to wear a thick coat, etc, but on the days when the sun is in full force with no clouds, it is like a sauna at times and I try to capitalize on those days. It will warm up your bones in an instant. On sunny winter days, it feels like the tropics.

On rainy days, the greenhouse can bring me some relief too. I suffer from tinnitus and the rain pouring down hard on the roof top is the most soothing sound to me, as it drowns out the ear ringing. Also, distractions drown out the ringing, so when I am creating or working with plants in there, it also brings me relief because I am distracted and in the “zone.”

We just did the ol’ “fall back on the clocks,” and this is a time of year of transition. It will be darker out at dinner time and dark out when we get up. I will try to not let that bring me down. The thing that keeps me up is knowing the holidays will be near and that I will be making wreaths soon, right after the Thanksgiving weekend.

Wreath by Cathy T

While times are tough, there are shortages of supplies, and also many prices increases for us all around, I still will attempt to make the most beautiful wreaths possible. If you are looking for a hand-made wreath, kissing ball, or boxes of greens, look me up if you are near me. All is arranged as porch-pick up’s and are noted on my site called, www.WorkshopsCT.com.

Well, not much else to report today. I basically wanted to make sure I record the date of our fall frost, because it is important for next year to remember when it comes around. Each year is slightly different.

Enjoy today’s sunny weather!

Fall is Fantastic

2 Comments

We are having a wonderful spout of good weather in Connecticut this year, 2021, during our fall season. The temps have been just lovely, no more rain (like we had all summer practically), and minus the mosquitos here, the fall weather has been fantastic to continue my various plant projects.

I am still taking down some of my tropical plants at home to store and overwinter, while finishing up some container garden installations for the fall season for clients, and also making beautiful custom made succulent topped pumpkin centerpieces for my orders.

I thought I would show some photos of various projects I’ve been doing, jumping from one project to another this month of October 2021 in Connecticut.

Cathy T holding a banana leaf Oct 2021

Well, here I am, holding a very long banana leaf from my red banana plant (Ensete ventricosum ‘Maurelli’). It is not hardy to our zone (6b) so I take it down every fall. It has become a ritual. I never had any issues with storing it as described on this blog via other posts (search Overwintering or Ensete), but this past spring, when I took the “stump” out of the storage bin, it was a little more damp than usual. I figured it was due to no air holes in my bins, so I drilled some very small air holes in the bin covers for this season. Or maybe it was the “new peat” I bought that stayed too damp, I’m not sure, but I have done this process again! Cutting down each leaf, chopping off the top of the plant, then storing the base. (See more photos below). People liked this photo when I shared it because it really shows the size of the planter, the plant’s leaves. I’m 5’6″…so, you can see how long these leaves grew this season in 2021. You may notice the plant is in a big black pot, I usually plant it directly into the big cement planter, but got lazy this year, and it did just as fine, the roots went thru the drain holes into the big planter below. I also fill this planter with Castor Bean plants, other Alocasia and Colocasia plants, and other perennials, etc.

Callicarpa Beautyberry Shrub Oct 2021

This is not a tropical plant above, it is a deciduous shrub, called Callicarpa. Just look at the purple berries this year! The foliage is a lime green (normal color). But this year, the berries have been abundant and really a deep purple color. I wondered if our abundant rainfall contributed to the color being so intense this season? I planted 3 of these side by side by my deck at the ground level years ago and I remember taking a measuring tape out to ensure I was giving it the recommended distance for spacing. People notice this shrub right now – it is beautiful. It makes a nice shrub for massing together as the branches arch and fill the area. I had cut it back in early spring and it performed nicely. I’ve never seen birds eat the berries, even though some sources say they do. I’ve never tried to grow it from seed, perhaps I should try to do so. Mr. Micheal A. Dirr’s manual indicates the seeds require 90 days cold stratification.

Cathy T holding a large Succulent Topped Pumpkin 2021

Yup, that’s me – trying to hold onto this very heavy and large succulent topped pumpkin I made for an order. Isn’t it beautiful – and so are the plants behind me! I could barely hold the pumpkin long enough for my husband to take a photo.

Ensete stump
Ensete stump

Referring back to the top photo of me holding the red banana plant leaf, here is the stump I dug out after chopping off the top. I use a machete. This stump was left in my garage for about a week, mostly because I was busy doing other fall plant project, but also to allow it to dry out somewhat. It is still moist from the water held in it, so a good suggestion is to tip it upside down and let the water drain out of it after removal from the pot or ground. I did have to cut off more of the top to fit it inside my storage bin which is about 3 feet long. The cover barely shut – this stump is a doozie! (That is heavy and big).

Container Garden by Cathy T in the month of October at a client site

If there’s one thing I will tell the plant Gods when I visit them some day, is, “THANK YOU!!” for offering me the wonderful opportunity to plant on a high rise. This is an October photo of just one of the many container gardens I install at this client site, and it is full and lush. I love how the fuzzy big leaves of the Lamb’s Ears plant grew extremely well, no blemishes, and as perfect as ever. It is called Stachys byzantina ‘Big Ears” and I guess you could say, I do have a fondness for big plants which make a big impact. It is a perennial plant for full sun (hardy to Zone 4). The silvery soft leaves are low maintenance and used as groundcovers, or in containers as I did here. I paired it with two flowering plants, one an annual and the other a tropical lover for hot sun. They looked just beautiful but it was time for the take down process this month. The nice thing about using perennials in containers is if you wish to move the pot (not doable in this case due to the location), you may do so to an unheated garage and there is a good chance the perennial will return the following spring. Or you may dig out the perennial from the container garden and plant it in the ground in the fall to continue your plant investment.

Mop Head Hydrangea Bloom at my House

I guess you could say, this month of October 2021 has been a very colorful one. This plant above usually hasn’t produced many blooms for me before, but this year, it took off. I had these big colorful blooms and I cut them from the plant just yesterday. I read you may spray the flower head with hairspray (aerosol hairspray) and set it in a cool dark room to dry. I am trying that out this season with these Hydrangea mop-head blooms in purple, blue, and rosy tones.

At a Client Site

A pumpkin centerpiece I created (referred to as a succulent topped pumpkin) is shown above at a lady’s home. I absolutely love how she decorates her table, putting the Family piece and candle holders with the mums all around. And a nice photo she took, which I decided to share here. Isn’t this another beautiful fall color photo? And yes, that is a real pumpkin, one of a nutty brown color. Sourcing my pumpkins was a little trickier this year. Many local farmers had issues growing them because of our summer abundant rainfall. Some fields were flooded and ruined some of the crop. I had to hunt and peck to find good ones for my succulent topped pumpkin creations this season.

More of my creations above. I love making these in October. I have made some Halloween themed too.

Me in-front of a Wall of Mandevilla

That is me again, here I am standing infront of a wall of Mandevilla plants I installed in the spring. By October, they were full and gorgeous all the way to the top of the 7 foot wall situated above planters. I have to say, I was distraught early this spring because right after I finished planting these, there was an extremely freak cold rain day where temps dropped so low and it poured, cold rain. I was so worried it would ruin my work at the client’s site, but the Mandevillas did well, and the rain all summer encouraged their growth. The foliage was shiny, perfect and lush. Each year is different, and I was so thankful these performed well. They have white trumpet shaped blooms that last all the way into the fall. These plants are vine-like growing easily up when trellised. They will keep on climbing, reaching for the skies, which they did here on this high-rise garden. I have planted the red, pink, white types. All add a tropical feel to any container gardens outdoors in summer.

Plant Gifts by Cathy T

Well, I guess that is it for now. I’ll finish off today’s blog post to remind everyone I offer custom plant gifts, especially popular in the autumn and at the holiday season. Look me up on Facebook or Instagram under Container Crazy CT. I do all in containers, planters, patio pots, dish gardens, etc. You name it. This month I’m offering adorable succulents, bagged up and ready for pick up. If interested, DM me on Facebook or text me!

Thank you and enjoy the rest of this week’s perfect and fantastic fall weather.

Today’s weather: 72 degrees F day, Lows at 48 degrees F at night (still safe for tropicals outdoors, I suspect the frost will arrive later next week!)

Tomorrow – partly sunny and Saturday and Sunday look nice during day. 37 degrees predicted for Sunday night.

Back to work I go outside today. Trying to make the most of this perfect fall weather, did I mention, it is fantastic?!

Overwintering Canna Lily Rhizomes Part II

Leave a comment

In my prior post, I detailed my process for overwintering my canna lily plant rhizomes in my area of Connecticut (Zone 6). I’m continuing it here for those who have asked questions (some asked in person and some via Facebook recently).

Basic Steps:

As noted on my prior post, cut down all the foliage, dig up the root ball, brush or wash away the soil, and let the rhizomes with a stalk attached air dry. After the rhizomes sat in the sun for a day, it was much easier to pull them apart to separate the rhizomes from larger clumps.

These rhizomes with partial stalks were left out on the table for a day in the sun

When I showed a friend how to do this process in person, she freaked out when I pulled the rhizomes by the stalks to separate them and then I started tapping the rhizomes on the ground to knock off more dirt. She was worried I was damaging them, and I said, “Oh, don’t panic, they will be fine.” I thought it was kind of funny but I get it – you don’t want to ruin them.

How to separate the big clumps

Sometimes when you have Canna Lily plants growing in a container for several years, when you pull the root ball out, it is one big clunk of a mass of roots and rhizomes all stuck together. It can be hard work to pull them apart. It is better to separate the rhizomes so when you replant them, they will be individual plants. The big clump over time will just not produce as nice of plants and will reduce the flowers. What I find is I try to separate them as much as I can and if they are really stuck together, let them sit in the sun for a day or two, and after it is dried out, take a stalk in each hand and pull apart and usually they will come apart easily.

Big Clumps “before” they sat in the sun for a day. Above photo this photo is after.

See the larger clump on the top right? That clump was much easier to separate after I let it sit in the sun for a day and overnight. Sometimes you will hear a “snap” like noise as you pull the stalks and the sections cracked away, and that is fine within reason. You basically do your best to separate them cleanly, but if they don’t – one or two cracks in the rhizomes is not going to ruin it all. After I separated them, I also cut the stalks to be about 4″ from the top of the rhizomes and let it all sit in the sun again for another day.

Preparing the Storage Bins

I store my canna lily rhizomes in plastic bins. Narrow bins work better. The deep bins are not necessary and if you stack too many rhizomes in a deep bin, they tend to rot more. So the narrow boxes are just right. You want to lay the rhizomes next to each other versus piling them up on top of each other for best results.

Last fall, I made the big mistake of not drilling some air holes in the new bins I had purchased, and some of my elephant’s ear tubers had rotted (ack!). Never again. So get your drill out and make holes the size of a pencil eraser. Not much bigger than that. You want little holes, not big holes. Also, put the peat moss about 1/3 of the bottom. Do not fill the container with the peat. You only need enough to allow a nice bed for the rhizomes to sit on with some of the peat poured over the top lightly.

Narrow Bins Work Best
Rubber Maid Box Lid

When I asked my husband if the drill was charged, he responded with, “What size drill bit do you need?” My response was, one the size of an eraser of a pencil. He got it. I don’t speak measurements well. Everything is visual for me! I want the holes to be tiny and just enough for some air circulation to occur in the box. It needs to breath just a little while it sits in my unheated basement for the winter months.

Label the box

I can’t stress enough the importance of labeling the box with the date and the items you put in there. I wrote it down in a notebook one year and then couldn’t find the notebook later! It just helps IF you are storing several types of tropical plants underground storage organs (tubers, rhizomes, corms, bulbs, etc.).

Stalks cut shorter, and allowed to dry in the sun again

After I trimmed the stalks to be shorter, I let them air dry again because otherwise that open fleshy wound could invite insects in the bin. It somewhat cures the rhizomes, you may also want to turn them over mid day to let it dry on the other side. Doing this on sunny days is best because if it rains, they get wet all over again.

One of the separations

More plants next season

One of the best motivators for doing all this work is you will end up with many rhizomes to plant when you bring them back to life in the spring time.

About the peat

Peat with some Perlite

About the peat

Does peat confuse you? It used to confuse me – cause peat moss is also used for hanging baskets or other projects in the gardening world. Do not use “Long Fibered Sphagnum Moss” which is used in hanging baskets, it is a more light dull brown color, and it does not work appropriately. It can hold onto moisture too much. The “Long fibered” moss, like shown in this photo below, is useful in craft projects, etc., but I find it does not work well for storing tubers, rhizomes, corms, etc. It stays too wet and doesn’t repel problems.

img
Do not use this type for storing the rhizomes

Use the brown spaghnum peat moss that typically comes in bags or square bales. It looks like this:

It looks like this without the white perlite

Last year, I had some extra perlite (white round balls in the photo below) which I tossed into a bin. Perlite is not in peat moss (just thought I’d mention that for observant people! LOL.).

In Bales or Half Bales

Available in compressed bales or half-bales

I’m not recommending any particular “brand” but usually I buy a compressed big bale like the one shown above, put it in a wheelbarrow, and break it apart with a small shovel. This type of peat is used in gardens, as soil amendments, and in potting mixes. It is used dry and I find it maintains well for several years, so the peat in my storage bins is reused over and over again “unless I had some type of bug or rot issue” in the bin which hasn’t occurred too much over the years. Also, I’ve read the peat moss’s acidic nature helps to keep problems out of the bin and away from the rhizomes. But we won’t go into that here, as I am trying to keep it simple. It is a great item to use because it retains a tad bit of any moisture just enough but allows air too.

Air holes along the top edge too

You will notice I drilled a few holes along the top edge of the bin too. If you are stacking these bins in your basement, the airholes on the top may be covered by the box above it so side holes are helpful.

Now, I’ve been told these things by people:

I just put my whole pot with the plant in the basement. (Yes, that works, but over time a big root ball in a pot won’t perform as well so eventually it is time to divide those rhizomes.)

I just put it in newspaper. (I am guessing this works but I trust my process and just keep doing it this way).

I just leave the canna plants in the ground. (Years ago, we could not leave the canna plants in the ground. They would freeze and die BUT I have found some that I planted in the ground next to my fireplace wall where the woodstove is used inside the basement, the canna lily plants have regrown. I believe the soil being a warmer in that area and the fact we have warmer temps from global warming has led to “some” canna lily plants surviving our winter ground temperatures, but I wouldn’t bet on it for any in containers left outdoors as they would certainly freeze. If you want to store the whole pot in the basement and not remove it to divide the plants, that is another option.)

I can’t be bothered with storing the rhizomes and will just get plants from you next year. (Yes! Sounds good to me. I grow many canna lily plants in spring and offer them for sale.)

Waiting on Storing this one!

Timing

All of this work may wait if you want to enjoy your tropical non-hardy plants here in CT, like this one I’m standing next to. I am waiting to do this one till at least early October because I am in love with this Alocasia. I almost lost tubers I had stored of these because of the non-air hole situation described above. The biggest leaf on this plant seems to be just getting bigger and bigger.

Gorgeous Alocasia Leaf 2021

Well, that’s it for today. I am continuing my work today outside here at my home. My husband has a joke that before we know it, it will be Halloween, then Thanksgiving, and then Christmas! I will say, “Stop saying that! Because I love my deck filled with plants and it depresses me to take all this down, but he is correct. Time flies when you are having fun.”

Thank you for visiting my blog.
