That's a lovely one, EJ. I don't know this particular one--it looks short, but I cant tell if that is so or if it is just the camera angle. It is lovely though.
I have never tried these but have admired them in the nurseries. Perennial? full Sun?? Excellent Photo!
Yes and yes stratsmom, ideally, but mine is in dappled shade so fewer flowers but my garden is a shakey one, and it does fab and the flowers burst out into the sunshine.
