Facts
Weeping forsythia is native to China and popularly planted in North America for its arching branches that bear numerous, early-blooming, yellow flowers. The tips of its arching stems can root when they touch the ground; thus, the plant can spread. Its stems can be trained to twine like vines, making for a nice privacy hedge or garden border.
Habitat
Anthropogenic (man-made or disturbed habitats), forest edges, forests, 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.
