How to grow
Sow the seeds in boxes in early summer or autumn. Plant out seedlings 15cm apart. It can also be grown by cuttings in early autumn or spring. Constant cutting will promote growth and prevent flowering.

Soil condition/position
Rich sandy soil 7.5cm deep in water 10cm deep. It can be grown in an ordinary garden i.e. not in running water, but this may not be very successful.

Small shiny rounded leaves on a fleshy stem. Grow to a height of about 30cm. Tiny white flowers in the summer develop into long curved seed pods. The plant has a peppery flavour.

Watercress is widely used as a salad vegetable. Infusions of young shoots are supposed to be good for arthritis, digestive problems and congested lungs. This remedy should not be taken for more than one week.
