Lynn: I know that Campanula punctata form, be sure to dead-head, and watch out for any tiny white rhizomes that could escape through the seams between concrete blocks.
Here's a photo of my nightmare, I can't possibly dig them all out (they're spreading into my lawn and the surrounding woodlands now), but to curb the seeding I yank out any and all flowering stems. Pretty monster isn't it
Campanula punctata (syn. C. takesimana, C. punctata var. takesimana)
Dirt (I feel odd calling you that, but that's your forum name): if looking for a new State and green place to garden, I recommend doing your research to make sure of the move. I moved from my home State of Massachusetts to the Seattle area back in the early 1980s, stuck it out for 4 years. Often touted as a great place to garden, the shock was discovering certain realities of gardening in that climate, the major one being armies of giant slugs that decimate herbaceous plants of most any type. For this die-hard New Englander I found the Pacific Northwest climate not to my liking, the long periods of cold rain & drizzle to be utterly depressing, so I moved back and have been here 30 years.
