A native of Europe and Asia, naturalized locally in North America, but often abundant where found, in disturbed ground, such as roadsides, and in moist forests, even swamps. Now a serious pest of forest understories in some areas. The spread of this species has been recent; the first collection was in 1956 in Kent Co.

The white petals are ca. 4–7 mm long and the fruit is a slender silique on a pedicel nearly as thick. It is a biennial, with ± evergreen basal rosettes whose leaves are more rounded than the stem leaves.
