I believe it's zone 8 where Peonies get iffy, but there are quite a lot of varieties known to perform well in gardens further south. Plants that actually like the cold make it easier for me to deal with winter, LOL.
I noticed that 'Pink Kisses', planted in early November, has pink growth buds at the soil surface now. Also saw red bud tips showing on 'Flame', planted last year. It's been pretty cold, so I think they'll stop there.
Annette, you mentioned getting a stem from the graft of that tree peony, was it grafted onto herbaceous peony rootstock? I had a tree peony at my last garden for several years, and suddenly one year a single pink herbaceous peony emerged right next to it, and bloomed! It freaked me out at first, I had no idea they were grafted. Did you see the pics of FrankRichards new plants? Those tree peonies looked to be growing on their own roots.
