Facts
Crested late-summer-mint is of Asian origin, and has been introduced in Europe and northeastern North America. It has the potential to be quite invasive. In Asia it has traditional uses as a medicinal and culinary herb.
Habitat
Anthropogenic (human-disturbed or -maintained habitats)
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.
