Perideridia gairdneri is a perennial herb in the carrot family. The roots have a
\npleasant sweet and nutty taste and can be eaten raw or cooked. It can be eaten in
\nquantity as a staple food. It is best used when the plant is dormant. The root can
\nalso be dried for later use or ground into a powder and used with cereals when
\nmaking porridges, cakes etc. The seed is used as a caraway-like seasoning, or can
\nbe parched and eaten in porridge or used as pi\u00f1ole. The young leaves are eaten
\nraw or cooked.<\/p>\n
Yampa is in flower from late spring, and the seeds ripen in the early summer.
\nThe flowers are hermaphrodite (have both male and female organs) and are
\npollinated by insects. The plant is self-fertile.<\/p>\n
The root is carminative, diuretic, mildly laxative and ophthalmic. An infusion
\nof the roots has been taken to counter the cathartic and emetic effects of another
\ninfusion. An infusion of the roots has been applied as a wash to sores and
\nwounds and also used as a nasal wash to get rid of catarrh. A poultice of the
\nroots has been used to draw inflammation from swellings. The juice of the slowly
\nchewed root is said to be beneficial in the treatment of sore throats and coughs.<\/p>\n
There is very little information on the cultivation needs of this plant and it is
\nunclear if it will be hardy in Britain, but judging by its native range it is likely
\nto succeed outdoors in most parts of the country. From its native habitat it is
\nassumed that the plant is fairly tolerant of soil conditions and of sun or shade.
\nYampa is a marvellous food plant that has been widely used as a staple wild food
\nby native N. American native peoples. It would be beneficial if the size of the
\nroot could be increased by selective breeding. In one trial transplanted roots from
\nthe wild to the garden grew three times their normal wild size under fertilized
\nirrigated conditions. Growing from seed is said to take four years to achieve
\na useable size and cold striation is required. Preliminary results suggest that
\ncutting and replanting the tops with some length of the root is the best way to
\npropagate these plants and obtain an annual crop of roots. Rooting begins early
\nin frosty cold soil conditions, and thus autumn planting is recommended with
\nseeds and root tops.<\/p>\n
