Have you got any kind of tarp, plastic or sheets you can use for coverings? I would put up some sticks or cages first, to hold coverings from squashing plants, then just cover the plants if possible. Pin down or weight the cover edges to prevent blowing off with a rock or piece of wood, just any heavier stuff. It is going to depend on how cold, how long, snow stays around, how much damage gets done.

I've been wondering the same thing. Supposed to get down to 28-30 tonight and tomorrow night. My peonies are all up and have buds. On one the foliage has turned green already and has buds the size of a nickle. I think maybe I should cover?

I wouldn't use plastic, as it doesn't breathe and tends to encourage mold and rot...Peonies are pretty tough. If you have expensive or delicate varieties by all means cover them. We are expecting a 32 degree night here Monday, and I don't plan on doing a thing. Mine have been just fine even after a sudden snow or frost.
