Comments
This naturalized, shade-tolerant European species can be very invasive in natural habitats, particularly bottomlands. A weedy form with short, swollen internodes below ground has become a persistent and noxious plant in cultivated fields in the Coastal Plain. Soreng (in FNA24) reports that ssp. trivialis is the only subspecies in North America.
Habitat
Floodplain forests, alluvial swamps, mesic upland forests (especially early-successional), moist to wet meadows, clearings, fields, and low roadsides. Common in the mountains and Piedmont; infrequent in the Coastal Plain.
Native Status
Introduced
