IdentificationHairy Bittercress is hardly hairy. Only the leaf stems are hairy, but not densely so. Stems are glabrous (vs. hairy basally in C. flexuosa/occulta). Its stem leaf segments are narrower than in other alien bittercresses. Plants produce a persistent rosette of basal leaves (absent at flowering time in C. pensylvanica).
