Facts
Leafy bush-clover originates from Japan, and only shows up in a few scattered locales in North America, including southern Connecticut and Cape Cod in New England. If is a leafy shrub, growing up to 2 m (6 feet) tall, with pink, pea-like flowers. Like many members of the legume family (Fabaceae), its roots form relationships with bacteria that help it fix nitrogen from the soil.
Habitat
Anthropogenic (man-made or disturbed habitats), meadows and fields
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.
