Edible Uses

Edible Parts: Leaves  Root
Edible Uses: Condiment

Root - raw or cooked[60, 61]. A pleasant sweet and nutty taste[2, 46, 95, 161], it can be eaten in quantity as a staple food[183]. It is best used when the plant is dormant[85]. The root can also be dried for later use or ground into a powder and used with cereals when making porridges, cakes etc[183]. The seed is used as a caraway-like seasoning, or can be parched and eaten in porridge or used as piñole[85, 177, 183, 257]. Young leaves - raw or cooked[257].

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Carminative  Diuretic  Laxative  Ophthalmic  Pectoral  Salve

The root is carminative, diuretic, mildly laxative and ophthalmic[94, 257]. An infusion of the roots has been taken to counter the cathartic and emetic effects of another infusion[257]. An infusion of the roots has been applied as a wash to sores and wounds and also used as a nasal wash to get rid of catarrh[257]. A poultice of the roots has been used to draw inflammation from swellings[257]. The juice of the slowly chewed root is said to be beneficial in the treatment of sore throats and coughs[213, 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.

Cultivation details

We have very little information on the cultivation needs of this plant and do not know if it will be hardy in Britain. Judging by its native range it is likely to succeed outdoors in most parts of the country. From its native habitat it is assumed that the plant is fairly tolerant of soil conditions and of sun or shade. Yampa is a marvellous food plant that has been widely used as a staple wild food by native N. American Indians. It is just asking for cultivation in order to improve the root size[85]. For polyculture design as well as the above-ground architecture (form - tree, shrub etc. and size shown above) information on the habit and root pattern is also useful and given here if available. The plant growth habit is a clumper with limited spread [1-2]. The root pattern is tuberous with swollen potato-like roots [1-2].

Propagation

Seed - we have no information for this species but suggest sowing the seed in a cold frame as soon as it is ripe. Alternatively, sow it in early spring in a cold frame. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse for their first winter, planting out in late spring of the following year. Division may be possible in spring or autumn.

Transplanted roots from wild to the garden grew three times their normal wild size under fertilized irrigated conditions. Growing from seed is said to take four years to achieve a useable size... cold striation required. Premliminary results suggest that cutting and replanting the tops with some length of the root is the best way to propagatate these plants and obtain an annual crop of roots. Rooting begins early in frosty cold soil conditions, and thus fall planting is recommended with seeds and root tops.
