Watercress is a trailing perennial vegetable of European origin with dark green peppery leaves. Plants usually grow in water. If you're fortunate enough to have a stream running through your garden, you can grow watercress on the bank. You can also grow it indoors in pots set in a tray of water. Watercress adds a kick to salad recipes and makes a popular garnish. It's full of vitamin C and minerals.

Although watercress is easily grown from seed, it is usually propagated in temperate climates from stem-pieces, which root easily in wet soil. Sow seeds of watercress directly in wet garden soils two to three weeks before the average date of last frost. Cuttings can be taken from the watercress you buy at the grocery. Watercress prefers sun in the North, dappled shade in the South.
Sow the seeds thickly 1/4 inch deep. Mulch lightly if high water is likely to wash seeds from their bed. As watercress becomes established, the plants will spread and float on the edges of streams, rooting into the soil below.
Pick plants when needed for a pungent, peppery flavor.
