With a peppery and pungent flavor, this ancient plant is popular around the world for its nutritional and medicinal value. High in vitamins A, C, and K, as well as providing potassium and calcium, watercress has been studied for its antioxidant properties. At home along streams and lakes, watercress can also be grown in moist, partly shady gardens and indoors in containers. When plants are 4"-6" tall, clip sprigs off the top; the tips are the sweetest, most tender part of the plant. In mild climates, harvest during the cooler parts of the year. | Botanical Interests Watercress Seeds
