Aegopodium podagraria — bishop's goutweed

Facts
Bishop's goutweed is widely planted in gardens and can be difficult to remove after it is established. It spreads primarily or completely by vegetative means, and it can be aggressive and crowd out native species. Although hard to eradicate, the cooked leaves are edible, so it can be held in check by harvesting the leaves. They lose a lot of volume in cooking, so one needs to collect more than appears necessary for a meal.
Habitat
Anthropogenic (man-made or disturbed habitats), floodplain (river or stream floodplains), 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.
