Facts
Split-lipped hemp-nettle is an exotic plant from Europe that has colonized northern North America, as well as Asia. It differs from brittle-stemmed hemp-nettle (Galeopsis tetrahit) in having a notched lower flower petal, and also in usually having pink flowers, whereas the flowers of brittle-stemmed hemp-nettle are usually white.
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.
