HOW TO GROW

Sowing: Start the seed indoors, pressing the seed into the surface of the soil in a germination tray. Make sure the tray has drainage holes, and place it in another container filled with 2-3” of water. Maintain the depth until germination, which usually occurs within 7-14 days. Transplant the seedlings to a stream or very wet area as soon as they can be safely handled.

Growing: Make sure the seedlings have constantly saturated soil; the plants can be immersed up to the tips of their leaves. These aquatic plants prefer cold, slowly flowing fresh water; for healthiest growth, they also need rich soil. This plant makes an excellent addition to marshy areas or water gardens; it can also be grown in containers with adequate moisture.

Harvesting: Begin to harvest the fresh leaves after 45-50 days of growth. Cut about 6” down from the tips. Use the leaves as soon as possible, since they do not store well. Continue to harvest only until the plant begins to produce flowers, since this makes the leaves bitter.

Seed Saving: After the flowers fade, the plant will produce long curved seed pods. Gather the pods as soon as they begin to turn color and the seeds inside have turned brown. Spread the pods out to dry, then crush them and separate the seeds from the pods. Store the seed in a cool, dry place.

DESCRIPTION

This flavorful, peppery plant has a history of being one of the most ancient leaf vegetables known. It contains many valuable vitamins and minerals. In the United Kingdom, watercress was often served in a traditional sandwich at high tea; commercial growers still produce this plant, particularly in the southern part of Great Britain. The genus name “Nasturtium” comes from the Latin words for “nose-twisting,” a reference to the plant’s peppery flavor. It does not come from the same plant family as the common nasturtium, though the leaves have a similar taste.
