Facts
English cinquefoil is a trailing, creeping perennial native to the British Isles, where it inhabits well-drained, acidic soils of heaths, banks, and disturbed field edges. It has a patchy distribution in North America; in New England, it has been collected in Maine. In its home range, it can hybridize with erect cinquefoil, P. erecta.
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.
