I know our Wisconsin Peony Society will not be selling roots this year, mainly due to complying with natural cycle of peonies and proper planting time really being in the Fall, for best success. I understand though that there will be a peony grower there, not sure if they are selling actual peonies or not? WPS will be selling little seedlings, while they last.
ST52 are you in the Wisconsin Peony Society? If you aren't, you should consider it. There are nice events we do as well as educational opportunities. Always something new to learn.
