Dicentra formosa — western bleeding-heart
Copyright: various copyright holders. To reuse an image, please click it to see who you will need to contact.
Facts
Western bleeding-heart is native to the western states of the US. In New England it is known only from Massachusetts, where garden escapes may have naturalized. "Formosa" means "beautiful," which is an appropriate descriptor for its pale pink, heart-shaped flowers.
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.
