Camassia quamash (Pursh) Greene |
Quamash (Camassia quamash), also known as Small Camas, is a perennial herb. It is one species of the genus Camassia and is native to western North America in large areas of southern Canada and the northwestern United States, from British Columbia and Alberta to California and east from Washington state to Montana and Wyoming.
The pale blue to deep blue flowers grow in a raceme at the end of the stem. Each of the radially symmetrical, star-shaped flowers have 6 petals. The stems have a length between 30 cm and 90 cm. The leaves are basal and have a grass-like appearance.
The name Quamash is from Nez Perce qém’es, a term for the plant's bulb,[1] which was gathered and used as a food source by tribes in the Pacific Northwest. The bulbs were harvested and pit-roasted or boiled by women of the Nez Perce, Cree, and Blackfoot tribes. It also provided a valuable food source for the members of the Lewis and Clark expedition (1804–1806).
Quamash is not just an edible plant, it is also grown as an ornamental plant. Even in the wild, large numbers of quamash can color an entire meadow blue-violet.
While quamash is edible and nutritious, it may occasionally grow with Zygadenus species which are extremely poisonous and which have very similar bulbs.
There are eight subspecies:

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. Additionally the plant spreads by seed rather than by runners.
The Quamash has been a food source for many native peoples in the western United States and Canada. After being harvested in the autumn, once the flowers have withered, the bulbs are 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. People have also dried the bulbs to then be pounded into flour.[2] 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. In the Great Basin, expanded settlement by whites accompanied by turning cattle and hogs onto camas prairies greatly diminished food available to native tribes and increased tension between Native Americans and settlers and travelers.[3] Both the Bannock and Nez Perce Wars began after Nez Perce became incensed at the failure of the US government to uphold treaties, and at settlers who plowed up their camas prairies, which they depended on for subsistence.[4][5][6][7]
While Camassia species are edible and nutritious, the white-flowered Meadow death-camas 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.[8]
