Tough as old boots, mine are in pots, very pot bound, spend the winter unwatered in a cold greenhouse and April -oct outside. I've seen them growing outside in a few places in Scotland , usually scree gardens with rock overhangs etc. I think excellent drainage is more important than cold .
Looking good this time of year
Fancy growing one of these are they hard to grow ?? @kittoch 🤔
