Edible Uses
Edible Parts: Leaves;  Seed.
Edible Uses: Condiment.

Leaves - raw or cooked[2, 5, 7, 9, 16, 27]. Exceptionally rich in vitamins and minerals, especially iron[200]. The leaves are mainly used as a garnish or as an addition to salads, the flavour is strong with a characteristic hotness[183]. The seed can be sprouted and eaten in salads[183]. A hot flavour. The seed is ground into a powder and used as a mustard[46, 183]. The pungency of mustard develops when cold water is added to the ground-up seed - an enzyme (myrosin) acts on a glycoside (sinigrin) to produce a sulphur compound. The reaction takes 10 - 15 minutes. Mixing with hot water or vinegar, or adding salt, inhibits the enzyme and produces a mild but bitter mustard[238].

Cultivation details
Watercress is easily grown when given the correct conditions of slowly flowing clean water, preferably coming from chalky or limestone soils[264]. It prefers to grow in water about 5cm deep[37] with an optimum pH 7.2[200]. Plants can be grown in wet soil if the position is somewhat shaded and protection is given in winter, though the flavour may be hotter[27, 37]. Plants are hardy to about -15°c[200], they tolerate somewhat lower temperatures than the closely related N. officinale[200]. Watercress is often cultivated for its edible leaves, there are some named varieties[16, 183]. The plant is very sensitive to pollution so a clean source of water is required[200]. Plants will often continue to grow all through mild winters. A fast-growing plant, the stems trail along the ground or float in water and produce new roots at the leaf nodes, thus making the plant very easy to propagate vegetatively[238]. Unfortunately, virus diseases have become more common in cultivated plants and so most propagation is carried out by seed[264]. This is a triploid species. It has hybridised naturally in the wild with the diploid species N. officinale to produce the sterile hybrid N. x sterilis which is also commonly cultivated as a salad crop[264]. The flowers are a rich source of pollen and so are very attractive to bees[7].
Propagation
Seed - sow spring in a pot emmersed to half its depth in water. Germination should take place within a couple of weeks. Prick out seedlings into individual pots whilst they are still small and increase the depth of water gradually until they are submerged. Plant out into a pond in the summer. Cuttings can be taken at any time in the growing season. Virtually any part of the plant, including a single leaf, will form roots if detached from the parent plant[56]. Just put it in a container of water until the roots are well formed and then plant out in shallow water.
