Does this look like a Chinese Yellow? Is it true that they are winter ground hardy in zone 7b? Just want to make sure that I don't have to take it in this winter!
Yes, that looks like Musella lasiocarpa to me. I'm in 7A and had one die after a cold winter in a colder part of my yard, but the one in a warmer area survived and has gotten very large and bushy with many pups. So I would think in 7B, it should be no problem.
