Facts
Brook lobelia is a native lobelia of northern North America. In New England it is absent from the Southeast. It inhabits fens, stream shores, seeps and river shore outcrops. The Cree and Iroquois used the plant internally as an emetic, or topically to treat abscesses and earache.
Habitat
Fens, ridges or ledges, shores of rivers or lakes
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.
