Is leadwort/plumbago that invasive in Zone 5?
I am planting a shade garden in the back part of my property next spring & wanted to use ceratostigma plumbaginoides (aka leadwort or plumbago). Its colors are GORGEOUS in the fall! My site is fairly protected b/c it's a city lot w/ lots of houses nearby. If I were to plant plumbago & it did "wander," how easy is it to rip up? Perhaps it wouldn't be as invasive in a Zone 5 site? (it's listed as Zone 5-9). I don't want to give it up but I also don't believe in maintenance heavy gardens. Suggestions? Thanks!
