Facts
Greater celandine is a Eurasian import, somewhat similar to celandine poppy (Stylophorum diphyllum), a plant native to North America. Greater celandine possesses a highly irritating sap that is sometimes been used to treat warts. Some plants are known to produce flowers with double corollas.
Habitat
Anthropogenic (man-made or disturbed habitats), forest edges
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.
