Camassia quamash, commonly known as camas, small camas,

native to western North America in large areas of southern Canada and the northwestern United States
.

Description

It is a

basal rosette.[citation needed
] The stems are between 30 and 90 centimetres (12 and 35 inches) long.

The pale blue to deep blue flowers appear in late spring to early summer (May to June in their native habitat). They are arranged in a raceme at the end of the stem. Each of the radially symmetrical, star-shaped flowers[5] has six tepals, about 2.5 cm (1 in) across, and six stamens.[4]

The plant and its bulbs are similar to the toxic white-flowered meadow death-camas (which is not in Camassia, but part of the genus Toxicoscordion, which grows in the same areas).[6][7]

Taxonomy

C. quamash subsp. maxima

There are eight subspecies;[8]

  • Camassia quamash subsp. azurea – small camas
  • Camassia quamash subsp. breviflora – small camas
  • Camassia quamash subsp. intermedia – small camas
  • Camassia quamash subsp. linearis – small camas
  • Camassia quamash subsp. maxima – small camas
  • Camassia quamash subsp. quamash – common camas
  • Camassia quamash subsp. utahensis – Utah small camas
  • Camassia quamash subsp. walpolei – Walpole's small camas

Synonyms

The superseded name for Camassia quamash subsp. quamash, Camassia esculenta (Nutt.) Lindl.,[9] should not be confused with the superseded name Camassia esculenta (Ker Gawl.) B.L.Rob., (nom. illeg.) for Camassia scilloides.[10]

Etymology

The

Blackfoot
tribes.

Distribution and habitat

C. quamash subsp. maxima, Skagit County, Washington

The species 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
.

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.[11] 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.[12][13][14][15]

Cultivation

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.

Uses

Camas is grown as an ornamental plant. Even in the wild, large numbers of camas can color an entire meadow blue-violet.

Food

The bulbs of this Camassia species are edible and nutritious when roasted or boiled,[16] but should not be confused with the toxic white-flowered meadow death-camas; the bulbs are difficult to distinguish.[6][7]

Camas has been a

Coast Salish, Lummi, and Blackfoot tribes, among many others. Camas bulbs contributed to the survival of members of the Lewis and Clark Expedition
(1804–06).

Camas bulbs (and bannock made from them) are listed in the Ark of Taste.[21][22]
