I bought one from a nursery and loved it so much that I bought several more in body bags. They made it through winter with very little die back, and our temps went to -10° this past winter! Even the puny body bag ones survived, which is saying a lot! None are planted in a particularly protected part of the garden, either.
I love the unique color combination on this one. I will be sure to post pics when it starts blooming, which should be soon.
