Watercress

Usually seen naturalized on stream banks, this water loving herb is known for its sprightly taste. Many gardeners don‰Ûªt realize that watercress can grow beautifully in containers or very moist areas of a garden, as long as it receives regular ample watering and part shade in hot climates. It is a hardy perennial which forms a dense spreading mat of bright round, green leaves with delicate white blooms. Hardy to all zones.
