I bought mine because it was suppose to be drought tolerant once established & I am planning on putting it in a rock garden i'm working on.Maybe i will have luck with them.
I did read while researching them they can die out in the center and you can give them a severe pruning & they will come back?? I think i have a lesson or two ahead of me with this plant.
but it's so pretty and that's how we learn the most.
