They bloomed every single year - they are typically hardy to Zone 7 throughout the southeastern US. I had a 100% positive experience with mine, but as I stated, it was sited in full sun/sharp drainage. There were more than several winters with temperatures in the teens & a couple times, single digits. There were never any problems with freeze/thaw, resulting in split trunk & branches. I think they're pretty sturdy, and I wish more folks would give them a try. I really appreciate plants of any type that are so trouble-free! I wish I had a spot where I live now: I saw the purple-leaved varieties & thought about a large container situation, but quickly put that to rest: that's really pushing the limits! I looked for a photo last night, but couldn't find them. Perhaps on my FB page. If I find, I'll post.
