Facts
Hedge maple is native to Europe, where it commonly inhabits hedgerows between farm fields; hence its common name. It tends to branch near the ground (and tolerates heavy pruning), giving it a shrubby look, like a scruffy Norway maple. Like Norway maple, it has milky sap.
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.
