Facts
White trout-lily is a very attractive wild flower of eastern North American forests and woodlands. It is not native to New England, where it is known historically from a single population in Connecticut. As an early-blooming wildflower it is sometimes cultivated in gardens.
Habitat
Forests, shores of rivers or lakes
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.
