Spreading explosively in recent years and now abundant along many major highways and river floodplains in the Piedmont and mountain regions.

A ruderal of mowed highway medians, shoulders, and cut slopes as well as fields and weedy alluvial soils. Infrequent to locally common in the Piedmont and mountains; rare in the Coastal Plain.
