With Swensons, I would rather wait a few years to hear of the track record on some of these peonies and I don't feel they have that yet. Introducing scores of peonies in a year doesn't seem like a careful eye with careful selection. I am not a professional, but I have listened to enough reputable growers in my life to know it can be a flag, so to speak.
Pretty pictures are a nice way to get through the winter though.
