Facts
Pustulose viper's-bugloss is native to southwestern Europe, and rarely visits New England, having been collected only in Massachusetts. It also occurs in scattered states of the eastern United States.
Habitat
Anthropogenic (man-made or disturbed habitats), marshes
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.
