Watercress is a peppery, aquatic herb which belongs to the green mustard family. Traditionally, it has medicinal value as a stimulant and laxative. It is available throughout the year, even in southern states (due to hothouse cultivation). The young shoots are often eaten raw (e.g. in salads). Otherwise, chop finely and stir-fry; add to pork or chicken-based soups, or use as a garnish. Put it in a sealed plastic bag and store it in the refrigerator (to prevent from drying), where it can be kept for up to 3 days.
