Edible Uses

Edible Parts: Leaves  Root
Edible Uses:

Root - raw or cooked[46, 61, 161]. It has a crisp texture and a pleasant pungent taste[43], rather like water cress or horseradish[183]. It can be added to salads or used as a relish[105, 183]. The root has a pungent acrid taste when first harvested, the Indians cleaned the roots, heaped them on a blanket, covered them to exclude air and then left them to ferment for 4 - 5 days. After this the roots developed a sweet taste[207]. Leaves - raw or cooked[257]. The cooking water was changed once in order to remove the bitterness[257].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Propagation

Seed - sow spring in a cold frame. Germination usually takes place within 1 - 3 weeks at 15°c[175]. When large enough to handle, prick the seedlings out into individual pots and grow them on in light shade in a greenhouse or cold frame for the first two years, planting them out when dormant in late summer. Division in early spring or after the plant dies down in the summer. Larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.
