Facts
Little hawkbit is introduced from Europe to North America. Within New England it has been collected in Massachusetts and Connecticut. A study of the advantages of having two types of seeds in little hawksbit found that seeds with pappus hairs (hairs at the tip of the seed that aid in wind dispersal) displayed few other characteristics beneficial to colonizing sites far from the parental plant, while those lacking pappus hairs were only marginally better equipped to replace the parent at the home site.
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.
