"Notes: This taxon occurs in many native habitats but also readily colonizes roadsides and waste places. Its native status is therefore uncertain (Rollins 1993)." [IFBC-E-flora]

"Habitat / Range Moist to dry streambanks, meadows, open forests, rock outcrops, roadsides and waste places in the lowland and montane zones; common throughout BC; E to PQ and S to GA and N CA; native status uncertain, also occurs in Eurasia." [IFBC-E-flora]
