Perideridia gairdneri is a species of flowering plant in the family Apiaceae known by the common names common yampah, Gardner's yampah and Squaw root. It is native to western North America from southwestern Canada to California to New Mexico, where it grows in many types of habitat. It is a perennial herb which grows to around .6–1 metre (2.0–3.3 ft). Its slender, erect stem grows from cylindrical tubers measuring up to 8 centimeters long. Leaves near the base of the plant have blades up to 35 centimeters long which are divided into many narrow, subdivided lobes. Leaves higher on the plant are smaller and less divided. The inflorescence is a compound umbel of many spherical clusters of small white flowers. These yield ribbed, rounded fruits each a few millimeters long. The entire plant is edible, but caution should be maintained as it has a similar appearance to the carrot family's deadly water hemlock and poison hemlock. It was an important food plant, even a staple food, for many Native American groups, including the Blackfoot, Northern Paiute, Cheyenne and Comanche. It would seem certain that the term yampa would be a version on the Comanche name for the tuber, variously yap, and yampa. One of the main divisions of the Comanche, the Yapainuu, were named the yap eaters, whose chief was the famous Ten Bears. More commonly referred to as the Yamparikas, this division roamed in the Northern Oklahoma area in historic times. The tuberous roots could be eaten like potatoes, roasted, steamed, eaten fresh or dried, made into mush or pinole, used as flour and flavoring, and were also used medicinally. Meriwether Lewis encountered the plant in 1805 and 1806, referring to it as a species of fennel. This food root is called cawíitx in Nez Perce, sawítk in Sahaptin and yap in Comanche. Blackfoot Indians knew the root by the name nits-ik-opa ("double root") and by those tribes of the Pacific Northwest as either yampa, ipo, or sa'-hweet.

Description

A slender herb that does not have hairs. It keeps growing from year to year. It grows 40-100 cm tall. The root is spindle shaped. The leaves are compound and divided twice.

Edible Uses

The root can be eaten raw or cooked and has a pleasant sweet, nutty flavour suitable for use as a staple food. It is best harvested when the plant is dormant. The root can be dried for later use or ground into a powder and combined with cereals for porridges, cakes, and similar preparations. The seed can be used as a caraway-like seasoning, parched and eaten in porridge, or used as piñole. Young leaves are also edible raw or cooked.

Traditional Uses

The fleshy roots are eaten raw or boiled. They are also dried for later use. They can be used in soups.

Medicinal Uses

The root is carminative, diuretic, mildly laxative, and ophthalmic. An infusion of the roots has been taken to counter the cathartic and emetic effects of other infusions. The same infusion can be applied as a wash to sores and wounds, and used as a nasal wash to clear catarrh. A poultice of the roots has been applied to draw inflammation from swellings. Slowly chewing the root and swallowing the juice is considered beneficial for sore throats and coughs.

Distribution

It is a temperate plant. In Canada it grows in moist open woods at low and middle elevations. It suits hardiness zone 5.

Where It Grows

Canada, Mexico, North America, USA,

Propagation

No specific information is available for this species, but sowing the seed in a cold frame as soon as it is ripe is recommended. Alternatively, sow in early spring in a cold frame. Prick out seedlings into individual pots when large enough to handle and grow on in a greenhouse through their first winter, planting out in late spring of the following year. Division may also be possible in spring or autumn.

Other Uses

Attracts wildlife.

Other Information

The roots are often eaten by children.
