Camassia is a genus that historically used to belong to the lily family (Liliaceae), the Scilloideae family, or the Hyacinthinaceae family. Lately, using DNA studies and biochemical techniques, the APG II-group has reassigned Camassia to the century plant family (Agavaceae).

    Description

    ---

    Camas grow in the wild in great numbers in moist meadows from Southern British Columbia to Northern California and east to Utah, Wyoming and Montana.

    The plant has linear basal leaves which emerge early in the spring. It grows to 18-30 inches, 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 blue-violet.

    Cultivation

    ---

    The bulb grows best in well drained soil high in humus. It will grow in lightly shaded forest areas 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 as well. Additionally the plant spreads by seed rather than by runners.

    Uses

    ---

    Ornamental

    This bulb is a perennial which naturalizes well.

    Food source

    The Quamash was a food source for several native peoples in the western United States. The bulbs were harvested and pit-roasted or boiled by women of the Nez Perce, Cree, Coast Salish, and Blackfoot tribes. They even kept alive the members of the expedition of Lewis and Clark (1804-1806).

    Warning: While Camassia species are edible and nutritious, the white-flowered Deathcamas species which grow in the same areas are not, and the bulbs are quite similar.
