I lost Indian Giver last year, I was surprised when it didn't come back last spring, since I was under the impression it was pretty hardy, and was in a good bed and mulched.
As for this years losses, too early here. I do have some growth, but the rest are shivering. Even my daffodils haven't started blooming, although I did have blooms on my Lenten roses for Easter, and they are still doing well.
