The Common camas (the photo above) is the breviflora variety (Camassia breviflora). Upon seeing an abundance of camas flowers on the Lewis and Clark expedition, Clark wrote;
“… our camp is agreeable Situated in a point of timbered land on the eastern borders of an extensive leavel and butifull prarie which is intersected by Several Small branches near the bank of one of which our Camp is placed. the quawmash is now in blume at a Short distance it resemhles a lake of fine clear water, So complete is this deseption that on first Sight I could have Sworn it was water. …” [Clark, June 12, 1806, at Weippe Prairie, Idaho]
