Watercresses (Nasturtium officinale, N. microphyllum; formerly Rorippa nasturtium-aquaticum, R. microphylla) are fast-growing, aquatic or semi-aquatic, perennial plants native to Europe and Asia, and one of the oldest known leaf vegetables consumed by humans. They are members of the family Brassicaceae, botanically related to garden cress, mustard and radish — all noteworthy for a peppery, tangy flavour. The hollow stems of watercress are floating, and the leaves are pinnately compound. Small, white and green flowers are produced in clusters.Cultivation of watercress is practical on both a large scale and a garden scale. Being semi-aquatic, watercress is well-suited to hydroponic cultivation, thriving best in water that is slightly alkaline.
