Watercress

Hardy aquatic plant found along gently running streams but can be grown with success in gardens or pots, provided soil is kept moist in a shaded spot. Pungent young shoots, with smooth, shiny dark green and at times bronze coloured leaves, can be cut once a week.

Note: If a clean running water bed is available, raise seeds in a seed tray, and transplant to permanent water bed when 10-15cm high. Cut back any flowering stems that may appear.
