An Old World species now a familiar weed of roadsides, fields, and disturbed sites. The earliest Michigan collection dates from 1840 (presumably Macomb or Oakland Co.); it was well established across the Lower Peninsula by 1911 but apparently slow to spread in the Upper Peninsula.

The large blue heads are very colorful en masse, but the plant is generally rather coarse. Occasionally some heads are on elongate peduncles, and they may be rosy or white [f. album Neuman] rather than blue.
