About
Camassia leichtlinii, the great camas or large camas, is a species of flowering plant in the family Asparagaceae. This herbaceous perennial is native to western North America in British Columbia, Canada and California, Nevada, Oregon and Washington, in the United States.
Where it grows
It needs consistent moisture in the spring, but will not be harmed by seasonal drought once the seed capsules have matured and the leaves dried out. Camas stands can benefit from seasonal fires as well, as they aid in regeneration and reduce competition from brush and weeds.
Uses
The bulbs are edible, but must be baked at length. Traditionally, they were cooked in fire pits for at least three hours, and ideally for between one and three days. Caution should be taken not to confuse this species with the deadly meadow death-camas.
