Water cress is a perennial plant grown for the pungent leaves and young stems, which are widely used for garnishing and in salads. Commercially, water cress is grown in pools of gently flowing water. It also grows naturally in many streams. The leaves are smooth and compound, with three to a dozen nearly round leaflets. Plants can be propagated from seeds or cuttings. The leaves and stems are partially submerged during growth. Springs are usually the water source, since any contamination in the water would contaminate the cress.
Production in the U.S.: 349 acres reported, 1959 census.
Use: Mainly for garnishing, in salads and sandwiches.
Part consumed: Leaves and young stems.
