Several from the Palatine order last fall didn't survive the winter. Probably, they weren't planted right. The few that I overwintered bare root in my garage are blooming already. I'll order another this fall, but I think I'll go back to spring delivery. It wasn't the winter that hurt them last fall, though, it was my broken ankle! Lots of plants didn't get planted. They just sat in the shade house, waiting for me to recover.
