Watercress is an entirely edible plant with delicately textured green small leaves that generally have three ovately shaped lobes. The leaves sprout from thin succulent stems that all connect to a cluster of roots. The plant produces fragrant white flowers as it matures. At its height of maturity, watercress produces edible seeds, if left alone will self-sow. Each element of the plant carries flavors of pepper and mustard that become bolder with the plant's maturity or when grown out of season. Watercress provides a rich source of pollen, thus attracting bees throughout its flowering season.
