These folks are moving to zone 7A. We are in 10 A and that plant blooms every two or three weeks here...seems like every time it gets water it blooms. I read a bit on it and it seems to need a dry spell when not in growth, but here the only rain we get is in winter, and rarely get down to freezing. She loves that plant, but isn't a gardener, so ...? I love this one too. I've never seen a cactus that blooms like this...usually one bloom per season, but I swear if you spit on this one it would burst into bloom. It had 7 blooms on it a month ago.
