Facts
Long-headed windflower is native to sandy and rocky fields, hillsides and woodlands in all New England states. It is an upright, slender plant, and its cylindrical clusters of fruits (achenes) are also much taller than wide), giving it its alternative common name of "candle anemone" or "thimbleweed". When mature, the achenes are attached to white puffy tails and the cottony fruit cluster releases them to the wind. Its root system produces a substance, protoanemonin, that inhibits growth of other plants.

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.
