Botanical Description

Rorippa palustris, the marsh yellow-cress, is an annual to short-lived perennial herb of the family Brassicaceae growing 10 to 60 cm tall, with erect, branching, often hollow stems. The leaves are pinnately lobed to deeply divided, the lower ones stalked and the upper ones clasping the stem with small ear-like bases. The small flowers have four pale yellow petals roughly equal in length to the sepals, borne in elongating racemes. The fruit is a short, plump, slightly curved pod, much shorter and fatter than in many related cresses, held on spreading stalks. It flowers from late spring through summer. Native across the temperate Northern Hemisphere and naturalised widely, marsh yellow-cress grows on wet, muddy, often disturbed ground at the margins of ponds, rivers, ditches, marshes and seasonally flooded fields.
