They are very hardy here in Tennessee. It got down to 1˚ here, and they still look great. I have some in a whiskey barrel, and the weather didn't hurt them either. They need good drainage, but can tolerate our wet winters pretty well. If you get the variety 'Brakelights,' it needs better drainage than the others, but it's still easy to grow! I like that one a lot because it blooms more and the blooms are more red. They constantly put up offsets from the crown. You can remove them and make more by sticking them in a pot of soil for a few weeks. It's a very forgiving plant!
