I missed this thread somehow. It's a beautiful peony! It looks so full and settled. I wish I could tell you what it is, but after searching around, I can't say. Sometimes if you email a grower, they have more insight as to the many, many varieties of peonies and what it might be. Hollingsworth Nursery is a good place to start. It is certainly lovely! Let us know if you find the answer. That peony looks familiar!
