Any of about 33 species of flowering plants in the genus Paeonia, sole genus of the family Paenoiaceae, found in Europe, Asia, and western North America and known for their large, showy blossoms. Herbaceous peonies are perennials that grow to about 3 ft (1 m). Their annual stems bear large, glossy, much-divided leaves and produce large single and double flowers of white, pink, rose, and deep crimson. Tree peonies are shrubs about 4–6 ft (1.2–1.8 m) high with permanent rootstocks and woody stems that bear flowers varying in colour from white to lilac, violet, and red.
