Facts
A cultivated form of Fullers' teasel, having hooked bracts on the flower head, was formerly used to raise the nap on woolen clothing. This non-native species was also frequently used in funeral wreathes. It is sometimes still found growing in or near graveyards.
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.
