I have Sheila Beila. It has not done well here. You'd think it would since it is one of Dan Hansen's evergreens. It has never bloomed and is really rust prone. It has already shown rust this season, in February in fact. That is the only one I have. I am thinking of potting it up and and using it to test seedlings for rust resistance.
I would like to get something with some sculpted relief, but I don't want another rusty plant. I may try another one at some point.
Later: I realize that my post was not in the spirit of the request, and I apologize for that. You are looking for northern-hardy sculpted relief plants to add to your collection, and I had nothing to suggest, so I should have kept quiet. Good luck, and I hope you get some wonderful suggestions from others.
