English Name: Watercress
Latin Name: Nasturtium officianale
Low growing aquatic plant with a spreading habit. The small heart shaped fleshy leaves have a peppery mustard flavour. Leaves are rich in Vitamin C. Probably best to grow in a large pot or tub in Australia as prefers constant moisture. Perennial.
Harvest leaves as required but harvest often to encourage new growth. Use fresh or store in fridge for two days. Not suitable to dry.
Grow in a pond or a pot that is always wet and semi-shaded. In winter it may cope without being in water if the potting mix is always kept moist. Use high-nitrogen soil.
Leaves are used as a garnish or in salads, sandwiches and Asian soups. Japanese use leaves in tempura.
