I'm not certain, but I think this one is growing in my Mother-In-Law's cactus garden. I've been trying to identify her plants for her because she doesn't know what most of them are- she just plants 'em because they're pretty and sometimes forgets about the poor things! Anyway, hers are a good five feet high, unlike the tag that says they only get to three... Maybe hers is just happy where it is? I'll see about getting a piece of it and try to grow one myself. :)
