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.
Habitat
Anthropogenic (man-made or disturbed habitats), meadows and fields
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.
