Succulent crisp leaves have a pungent, peppery flavor, long considered a gastronomic delicacy. It is a very good source of vitamins A and C, and a good source of folate. Watercress is a favorite foraging plant; it’s typically found growing along bodies of running water like creeks. Watercress is easily cultivated in traditional garden beds or containers; this variety is particularly high yielding and well suited for home and market gardens.
