A weedy, alien semi-aquatic plant
Nasturtium officinale watercress

Add to MyPlants
Semiaquatic dark green, leafy plant of clear, cool shallow water of springs, seeps, and quietly flowing streams; submerged or partly emergent. Its hollow herbaceous stems are erect and roots tend to form at lower nodes. Leaves are pinnately compound and alternate on the stem. Tiny four-petaled white flowers form a raceme. Watercress is native to Europe but became widely naturalized in our state. The shoots of watercress have a pungent taste and can be used as a garnish.
