A common little Eurasian weed of roadsides and trails, disturbed areas in forests, on shores and rock ledges; in moist fields and gardens; and disturbed ground generally, such as parking lots, vacant lots. Collected by the First Survey in 1837, but without a specific locality (likely either Washtenaw or Wayne Cos.), collected shortly aferwards in Macomb Co. in 1843. and doubtless soon well established.
The style is ca. 0.5–1 mm long: often intermediate between style lengths of V. dillenii and V. verna, which resemble it. Pedicels are up to 2 mm long.
