We continue to add tree peonies to the Nichols Arboretum Peony Garden. These tissue-petaled peonies  have woody stemmed and bring colors to the garden not usually found in herbaceous peonies. Tree peonies also bloom earlier than herbaceous peonies, extending the bloom season into the second half of May. You’ll find tree peonies on the hillside and beds on the east side of the main peony garden beds. Check out this gallery of some of our tree peonies. All photos by Michele Yanga
