Facts
Mountain death camas is very rare in New England, being known only from the shores of Lake Champlain, Vermont, where it grows on lakshore headlands and bluffs on high-pH bedrock. It is poisonous to humans and cattle, and a common source of poisoning in sheep. The flowers have a characteristic unpleasant odor.
Habitat
Cliffs, balds, or ledges, 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.
