Small flowered winter-cress

Small flowered winter-cress is a biennial to short-lived perennial herb in the mustard family, well suited to damp, disturbed soils along stream banks, roadsides, and garden edges in temperate climates. It requires minimal care, tolerating partial shade and consistently moist to wet soil, making it useful as a naturalizing ground cover in rain gardens or boggy areas. Yellow flowers appear in late spring, providing an early nectar source for pollinators before the plant sets seed and self-sows.
