Facts
Crown daisy is introduced from Eurasia as a garden ornamental, and is an occasional escapee in New England. The young shoots, young leaves and flower petals of crown daisy can be eaten raw or cooked. A fragrant pickle known as 'kikumi' is made from the petals in Japan.
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.
