I never want to add an invasive plant to a garden design by mistake. So I try to keep up with news on the subject, attended a CHS ed session about invasives last Sat. Interesting story I heard was how invasive Japanese Barberry (Berberis thunbergii) was attempted to be controlled by burning the bushes in an area, mice scattered everywhere looking for new homes (and as we know, mice play a role in tick problems in CT). Thus more barberry in the woods, more problems with ticks! Speaking of burning bushes, burning bushes (Euonymus alatus) are also very invasive. Try Highbush Blueberry as a great native alternative that has the similar effect of beautiful red foliage in the fall. For more, see www.conservect.org/ctrivercoastal.
