Q: What is the difference between tree and herbaceous peonies? A: Tree peonies have woody above ground stems that remain throughout the year, much like a small shrub. The leaves however are deciduous and fall each autumn. Herbaceous peonies die back to the ground each autumn. Both types of peonies form the next year's buds each fall. Tree peonies form these buds mostly on the above ground stems. Herbaceous peonies form these buds on the underground crown of the plant. This difference accounts to a large degree in the difference in hardiness. Herbaceous peonies will thrive in northerly climes too cold for tree peonies.
