Facts
Garden pea (Pisum sativum) is a widely cultivated plant, and hundreds of forms have been developed. Its domestication dates back at least 3000 years in southwestern Asia, and seeds have been found in archaeological sites dating back at least 6000 years. Escapes have been reported in scattered locations across North America, including New England.
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.
