OK - I'm rethinking cooperi....
1 - I loved it because in the pictures it's PURPLE. You said pink.....
2 - invasive????? I'd rather not, but if it's evergreen and PURPLE, not pink - I hate pink - it would be a good groundcover for my tiny front yard in lieu of grass to have to mow.
everybody chime in and tell me what color YOUR cooperi blooms, please - before I invest....
