Cusick's Camas (Camassia cusickii)

Camassia is a genus of six species native to western North America, from southern British Columbia to northern California, and east to Utah, Wyoming and Montana. Historically, the genus was thought to belong to the lily family (Liliaceae), sometimes narrowed down to the families Scillaceae or Hyacinthaceae, but DNA and biochemical studies have led the APG II-group to reassign Camassia to the family Agavaceae. Common names include Camas, Quamash, Indian hyacinth, and Wild hyacinth.

Camas grow in the wild in great numbers in moist meadows. They are perennial plants with basal linear leaves 20–80 cm long, which emerge early in the spring. They grow to 30–130 cm tall, with a multi-flowered stem rising above the main plant in summer. The six-petaled flowers vary in color from pale lilac or white to deep purple or blue-violet. They sometimes color whole meadows.

Species
  • Camassia angusta - Prairie Camas
  • Camassia cusickii - Cusick's Camas (occurs in eastern Oregon)
  • Camassia howellii - Howell's Camas
  • Camassia leichtlinii - Large Camas, Great Camas (occurs west of the Cascade Mountains from British Columbia to the Sierra Nevada).
    • Camassia leichtlinii ssp. leichtlinii : Large Camas
    • Camassia leichtlinii ssp. suksdorfii : Suksdorf's Large Camas
  • Camassia quamash - Quamash, Indian Camas, Small Camas.
  • Camassia scilloides - Atlantic Camas, Bear grass (occurs in the eastern United States in North America. The habitat extends along the Atlantic states from Maryland to Georgia and westward to Texas. It also includes the upper midwest states of Michigan and Wisconsin.)

[edit] Cultivation and uses

Ornamental use

This bulbflower naturalizes well in gardens. The bulb grows best in well-drained soil high in humus. It will grow in lightly shaded forest areas and on rocky outcrops as well as in open meadows or prairies. Additionally it is found growing alongside streams and rivers. The plants may be divided in autumn after the leaves have withered. Bulbs should be planted in the autumn. Additionally the plant spreads by seed rather than by runners.

Food use

The Quamash was a food source for quite a number of native peoples in the western United States and Canada. After being harvested in the autumn, once the flowers have withered, the bulbs were pit-roasted or boiled. A pit-cooked camas bulb looks and tastes something like baked sweet potato, but sweeter, and with more crystalline fibers due to the presence of inulin in the bulbs. When dried, the bulbs could be pounded into flour. Native American tribes who ate camas include the Nez Perce, Cree, Coast Salish, Lummi, and Blackfoot tribes, among many others. Camas bulbs contributed to the survival of members of the expedition of Lewis and Clark (1804-1806).

Though the once-immense spreads of camas lands have diminished because of modern developments and agriculture, numerous Camas prairies and marshes may still be seen today.

Warning: While Camassia species are edible and nutritious, the white-flowered Deathcamas species (which are not the genus Camassia, but part of the genus Zigadenus) that grow in the same areas are toxic, and the bulbs are quite similar. It is easiest to tell the plants apart when they are in flower.
