A member of the Brassicaceae family, Nasturtium watercress is a semi-aquatic herb that can easily be grown in somewhat moist soil or hydroponically in alkaline water. A native of Southeast Europe and the Mediterranean, Nasturtium watercress has been in medicine for centuries for it’s healing properties. The thin hollow stems of the herb containing green ovoid leaves grow from a flock of herbs. Once the plant matures and goes into flowering, it produces small white flowers with edible seeds. Both the stems and the leaves of the herb are edible and have a sharp, peppery flavour which can be used raw in place of salad greens or cooked in soups or vegetables recipes. Nasturtium watercress is a good source of vitamins A, and C, potassium, calcium and magnesium.
