Facts
Japanese angelica-tree is native to temperate Asia. It has exceptionally large, compound leaves 2 to 4 feet long, borne on stems with large prickles. Its suckers can spread rapidly. Various cultivars have attractive, variegated leaves; however, they involve grafting and are expensive and difficult to propagate.
Habitat
Anthropogenic (man-made or disturbed habitats), forest edges, meadows and fields, 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.
