Coefficient of Wetness:
A northern species of cliffs and ledges; our commonest rock-dwelling species of Draba, and the only one likely to be encountered in the state by most botanists, though very local except on Isle Royale.
Distinctive among our species in its twisted fruit, although a few specimens do not show this twisting very clearly. A few collections are unusual in having somewhat pubescent young fruits, but can be told from D. cana by their longer anthers (0.4–0.6 mm long versus ca. 0.2 mm).
