Lespedeza cuneata — Chinese bush-clover

Facts
Chinese bush-clover is native to eastern Asia, and introduced in North America, where it can become very invasive, forming dense stands that crowd out native vegetation. This spread has been rapid, largely originating from deliberate plantings in the 1940s to the 1990s, resulting in 8.6 million acres (3.5 million ha) of the United States being infested by 2003. New England is at the northeast limit of Chinese bush-clover's current range, and it so far appears only in Connecticut and Massachusetts.
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.
