Quick facts
Nasturtium officinale
Watercress is a popular plant the world over. High in vitamins A, C, and K, potassium, and calcium, the leaves have a pungent and peppery flavor. More mild if it is grown in the shade, is well-watered, and grown in cooler weather, watercress thrives in very moist places in the garden. Does well in both indoor and outdoor container gardens! Plants are small and round, measuring 10-14".
