Edible Uses

Edible Parts: Root
Edible Uses:

Tubers - raw or cooked[22, 46, 61, 85, 105, 161]. The tubers are rich in starch but are quite small, averaging only about 3cm in diameter[85, 95]. The tubers range in size from a pea to a walnut[216]. There is a bitterness in the tuber, this is concentrated near the skin[85]. They can be stored for several months or can be sliced thinly, dried and ground into a powder for making bread etc[183, 257]. The Hopi Indians cook them or eat them raw with a saline clay in order to counteract the astringency and also use them in making yeast[183, 257]. The tubers are rather fiddly to harvest, apart from their small size they are also produced at the tips of roots, often at some distance from the parent plant[K].

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.

Cultivation details

Succeeds in most soils[1]. Dislikes wet or heavy clay soils[16, 37]. Prefers a slightly acid soil, the tubers are subject to scab on limy soils or those deficient in humus. Yields best on a fertile soil rich in organic matter. Not very hardy in Britain, but plants can be grown as half-hardy perennials, the tubers being planted out in April and harvested in the autumn after the top growth has died down.

Propagation

Seed - sow early spring in a warm greenhouse. Prick out the seedlings into a fairly rich compost as soon as they are large enough to handle and grow them on fast. Plant them out after the last expected frosts. Division. Harvest the tubers in autumn after the top-growth has been cut back by frost. Store the tubers in a cool frost-free place overwinter and replant in April.
