* The Common Camas (Camassia quamash) species are part of one of the rarest ecosystems in Canada, the Garry Oak meadows which are endangered by development in southwestern British Columbia. Much of southeastern Vancouver Island was dominated by this ecosystem at one time. When settlers came they found vast open Camassia quamash fields already cultivated by the local population. These fields were perfect to introduce European crops to. Over time most of the meadows where turned over to crops and then to housing and commercial development. We are now learning to appreciate the importance of these areas and are trying to protect and reclaim areas from invasive and non-native plant materials.
** While Camassia species are edible and nutritious, the white-flowered deathcamas species (which are not in the genus Camassia but in a number of genera in the tribe Melanthieae) 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.
The quamash was 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 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. The Kutenai called the camas “xapi” (Ktunaxa). Camas bulbs contributed to the survival of members of the Lewis and Clark Expedition.
