Anya, there is info somewhere about old varieties, but none about new ones. So what are the most floriferous new cultivars? I guess new ones are not that impressive. What are they growing - only old ones? I got Mme. Claude Tain because it was considered a nice cut flower with great presentation in vase. See how it will perform.
Annie, I could not find info about growing for cutting on that website. Just individual peonies characteristics for vase life. I guess growers are not spreading it in the open. I can ask Top in a few years time for his favorites.
