Facts
Nuttall's poverty-weed is native to North America west of the Mississippi, from Mexico to Alaska. It is an uncommon visitor to New England, having been collected in Massachusetts and Maine on roadsides and disturbed sites. The Hopi People used the seeds of this plant for food.
Habitat
Anthropogenic (man-made or disturbed habitats)
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.
