Colorful Balcony Plants for Extreme Weather

Leave a comment

These are photos of vivid reds and yellow blooms in large patio pots showcased on a high-rise balcony. As you can see, the yellows and reds of the flowers on these plants stand out. They are also very drought tolerant. And full sun lovers.

I planted this combination on a high-rise balcony many years ago. The conditions up there were brutal in the summers at times. It was very sunny and hot for the first half of the day. The second part of the day was shaded due to the height of the building’s walls and the sun’s movement. But it also was extremely windy at times, and as hot as a very hot beach summer day. Notice in the next photo how much the blooms opened up.

The pots shown here were quite large. Plenty of quality potting soil was used. Some soil moist was added to help manage moisture levels. I also added slow-release fertilizer into the soil. But it was key to find plants which would survive the high-rise conditions. They must get water too. It was imperative to find plants with strong abilities to survive in the sun, wind, and heat. These plants did this well. These also did not need lots of clean up. The faded flowers of the Coreopsis are easy clipped off (deadheaded) if needed. All the other plants held onto the flowers in this combination.

As the summer progressed, the plants became full and offered super bright colors seen from afar. This was good. The view from the balcony owners’ large living room allowed them to see the reds and yellows. I also focus on different textures too. You can see the fine texture of the yellow Sedum. The larger oval leaves of the red edged Jade plant are also visible. Yes, a Jade (as in a houseplant). I never overlooked using houseplant candidates as well as perennials and tropical plants. Just like in a garden, textures add the drama and flow needed to please the admiring eye. I often held up plants next to each other. I did this to look them over and see if they seemed to work together. I was just like that with my eyes. I would figure out if they played well together visually. I also needed to know the plants’ overall habits and culture needs.

This is a Jade. It was a rather large plant. I loved the red edges. The red color only intensified in the patio pots with the full sun conditions. There was lots of warmth and heat on sunny days. These were able to withstand drought like conditions. I always emphasized that the owners should water every day. Plants need water. The soils dry out rather quickly up there on the top of a building in the city. And the owners were fantastic. They did water the plants as often as possible. They got an A+ on that as it wasn’t always easy, there were no faucets or hoses outside. All water was carried from the inside to the outside in buckets! When it rained, that was a bonus.

The yellow plant in the front is a Sedum. It is called, Lemon Ball Stonecrop Sedum. A perennial. Talk about an intensely bright yellow! Really pops. It was perfect for the front of the patio pot, tucked in nicely. That plant in this combination was a little more delicate. But, its vivid yellow was unbeatable.

And a must on everyone’s list is flowers which bloom most of the summer. I added these Coreopsis because of their beautiful yellow coloring with red centers. They also handled the drought conditions quite well. This one is called, ‘Baby Seed’ Tickseed Coreopsis. These are butterfly magnets and work well in rock gardens too. It was always a treat to see a bee or two. I enjoyed seeing a bee come by up there when I put flowers into the customer’s containers. Way up there. I think it was 26 floors high, or was it 28? I can’t remember, but it was up high. If you couldn’t handle heights, you would not be capable of work up there on their open balcony. It didn’t bother me to look over the railing to the city streets below. It was a unique planting experience and a great learning one too due to the high-rise location.

And there are of course the Mandevillas or Dipladenias. Big pretty blooms. Red on these and a vine-like habit. This one did not vine as much as others, but it was a staple for my balcony garden working days. They tolerate the winds, hold onto the flowers despite winds strong enough to move heavy furniture on the balcony. Furniture which had to be chained down appropriately always. Tropical plants they are.

Experiencing working on a high-rise balcony was one of my ultimate pleasures of having my former small plant related business. I only felt disappointed that they (the penthouse owner’s) did not discover me sooner. I wish I had worked up there when I was younger. I would have been able to handle more of the physical aspects. I was a solo worker. It was sometimes a challenge to figure out how to get all the soil bags, plants, and more up there. Because I am organized, I found ways to maximize my trips up the service elevator. I used wagons and a hand truck. I used the appropriate boxes and bins. I did it and I loved every minute of being up there. Well, maybe on those super-hot days, not so much. But I loved the plants and expansive balcony views enough to keep on working up there. It was an honor.

How to Determine which Plants to Bring Inside

4 Comments

I’ve been sharing my methods and timing regarding when to bring in outdoor plants (in container gardens or patio pots) indoors during the fall season to prepare for the winter months here in my area of Connecticut (Broad Brook/East Windsor, Zones 6).

But how do you actually determine which plants to bring inside and when?

Sometimes other factors come into play besides the lower temperature drops that some plants will not tolerate.

For example, this kitchen herb garden, which I planted for a client on a balcony, is booming still. I visited the site just yesterday, and look how large these herbs are in September. Amazing! All of the herb plants are still thriving and not showing much stress yet from being exhausted from growing all summer in the heat nor from drops in evening temperatures recently.

Herb Gardens at Container Crazy CT Client Site as of September 15th

It would be a sin to take these all down right now, don’t you agree? There still time to enjoy these wonderful, fresh, aromatic, and delicious herbs. Due to the full sun conditions and appropriate watering by my clients at their residence, their herbs are absolutely thriving.

I’m especially proud of these herb plants because many of the herbs in these planters were started from seed by me earlier in the season and planted as starter plants. I’m in love with how well they did and how amazing they taste. The clients are still enjoying every snip and harvest.

We decided to let them be for a while more. While my herbs at my home are dwindling, such as my basil (which prefers warmer temperatures than we get during our fall cooler temperatures), their herbs are still perfectly fine. They get more sun where they are located compared to my location.

MatchBox Peppers Grown by Cathy T of Container Crazy CT

Just look at these matchbox peppers, which I grew from seed earlier this year as well. They are booming with small hot peppers. They are tiny and super spicy. They completely cover this plant, which was described as compact. I’ve grown these in hanging baskets too and they are perfect for them. Of course, these can remain outdoors a couple more weeks until we get frosts.

Sometimes we get a few “light” frosts before a hard frost. Light frosts may occur as early as October 4th. A hard frost could be anywhere from mid-October to very early November, based on my experience and records. So, yes, you could decide to leave something like this herb garden growing a while longer to capitalize on the wonderful harvest. The key is to pay attention to the weather forecasts and your weather apps.

Skull Terrarium with Succulents and Cacti

Here is another example of a plant related item which could stay outdoors a while longer. It is a terrarium I made a couple seasons ago. I created it around Halloween and used decoupage glue to adhere a skull print on fabric inside of it. I remember thinking it would look super cool with plants.

You will notice the white area, ironically resembling a mask, which is where the glue will get wet. It left a white area mark there – so my test of this fabric has a flaw, or does it? It looks super cool to me.

I could leave this terrarium outdoors for a few weeks more here in Connecticut. Before any frost would hit it. But I wanted to move it indoors into my greenhouse before it gets waterlogged with rain. We initially had rain predicted for this Friday by our weather forecasters, but that seems to have changed to “chances of rain” now. Anyhow, the plants are thriving, there are no insect issues, so why chance it? It is easy to take inside to keep growing another season.

The key thing is things change fast in regards to weather this time of year. You may be humming along, enjoying your outdoor plants, and thinking it is so beautiful outside. It is warm, some flowers are still blooming, and the fall air is just right where you feel comfortable working outdoors in the 70 degree range. And the next day, it will be 80 degrees F out. Like summer! What’s the rush, right?

But there will be that night where it gets cold fast, like this Saturday, predicted to be in the 40’s. Still not freezing, still safe for many plants, but it is coming.

Determining what to move indoors has the factors of weather, upcoming freezes, but also, some of that determination is based on how you use the plants (or how you enjoy their show). As in the example of the herbs – still very much usable. Or, it could be how beautiful the plant is at the moment.

Supertunia annuals in full bloom and glory at the start of the fall season

Take for example, this dish garden, also at my clients’ site. Good Lord. Look at those hot pink Supertunia annual flowers. I gasped when I saw how much they grew from earlier this season to now in mid-September. Usually, I would take this dish garden away to take apart and store, but how could we? They are still amazing. And until they get hit by frost, might as well enjoy the show, right?

This dish garden also houses some amazing succulents. All look fabulousa. However, for succulents, I prefer to take special care with removing if you are taking them indoors. I prefer to move them before things get really damp and cold. With a drop in temperatures by the weekend at night, this could happen. Then tender succulent plants may start to suffer. If you are not taking them in, you may risk it and keep them outdoors. But most non-hardy tender succulents, in my opinion, should be moved in before it starts to get chilly consistently in the low 50’s and 40’s.

Succulents still thriving but Moving them in Before Cold Rains is Smart

What happens this time of year is we get temp swings. All will humm along fine and then BAM! It will turn cold and you will be taking out your favorite sweatshirt. As for myself, getting some of this moving in container work done early may be a bummer because you want to enjoy the beautiful creations a while longer, however, I never regret getting some of it done ahead (before warm gloves, sweatshirts, and my warmer hiking boots are required.)

And another factor is the fall mums we have available around here in Connecticut this time of year. If you are going to display them, you might as well get them out soon so you may enjoy them throughout the fall season. There are tons of mums around to be had. Some places sell out of mums by mid-October, so you want to get them soon so you can enjoy them for a while before snow comes right?

Did I say snow, OMG, don’t even go there Cathy! LOL.

Don’t forget! Towards the end of September, it is succulent pumpkin creation time. I will have some succulent new stock available if locals are interested! I will post photos on my usual feeds. If interested in a custom made succulent topped pumpkin, now is the time to give me the order.
