Camassia leitchlinii ‘Blauwe Donau
 

Extra notes and interesting information:
When it flowers in early spring, camas produces large fields of blue that, from a distance, resemble pools of water.

Camas has been one of the most significant staples and monetary plants of Western Indians. The bulbs are dug in spring but care must be taken not to collect death camas (Zigadenus venenosus). Camas bulbs are either cooked, producing a sweet gummy taste, or dried for later use.
