Other info. - This delicately beautiful species is found across most of Missouri, except for the far northwestern and southeastern corners of the state. Its U.S. distribution is restricted to the eastern half of the country. It is probably more abundant in Missouri than any other state. Its showy inflorescences are easily recognized, although can be easily confused with those of Missouri's other member of the genus, C. angusta. The latter species is far less common, and is distinguished by having more flowers on the inflorescence and up to 24 stem leaves.

The flowers of this species are variable in color, ranging from pale blue to white. The bulbs are edible and those of western species have been used as a food source by Native Americans. Bulbs of eastern species are normally cooked before being consumed. Great care must be taken in tasting the bulbs, since there are many highly poisonous plants which look similar. Camassia scilloides is popular among insects, and seems to be a favorite of beeflies.
