Facts
Running groundsel can form large, clonal colonies in wet sites.
Habitat
Forests, woodlands
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.

Native to North America?
Yes
Sometimes confused with
- Packera paupercula:
- plants without stolons and the leaf blade not decurrent on the stalk or only scarcely so (vs. P. obovata, which are plants with stolons, forming colonies, and the leaf blade decurrent on the stalk).
