Penstemon barbatus — beard-lip beardtongue

Facts
Beard-lip beardtongue is native to North America, but in New England it is considered introduced, probably as a result of cultivation in gardens for its showy, tubular red flowers. In our region it is known only from waste areas in Massachusetts. The genus name derives from the fact that flowers have five stamens, one of which is sterile and surrounded by hairs (hence, "beardtongue."
Habitat
Anthropogenic (man-made or disturbed 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.
