Facts

Chinese peony is a garden plant native to Siberia and Mongolia and has been introduced to North America. In New England it has been collected as a garden escape only in Vermont and eastern Massachusetts. Widely cultivated in China for its medicinal properties, its roots are harvested from 5-year-old plants, dried, and made into a soup which is helpful as a woman's tonic for cramps and other maladies. It is distinguished from the common peony (P. officinalis) by its leaves, which have finely serrulate edges, and its fruits (follicles), which are smooth.
