English Name: Watercress
Latin Name: Nasturtium officianale
Description:
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.
Height 30cm.
Harvesting:
Harvest leaves as required but harvest often to encourage new growth. Use fresh or store in fridge for two days. Not suitable to dry.
Best Results:
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.
Uses:
Leaves are used as a garnish or in salads, sandwiches and Asian soups. Japanese use leaves in tempura.
