Thank you Chris for your question to "Ask Extension".  In order to continue researching your plant's problem I would like some additional information.  A picture of your plant and planting site.  What was the size of your camas bulb?  How deep did you plant the bulb?  The type of soil it was planted in?  And how much sun does the site receive?
     Thank you in advance.

Camassia quamash (common or small camas)

Photo is below. It was taken at about 6 p.m. last night.

I don't know the size of the bulb. It was in a container and was about to bloom when I got it. The hole was deep enough to where the potting soil in the container was even with the soil.

I have no idea the type of soil. It gets several hours of direct and indirect sun each day,

     Thank you Chris for your quick response and photo.  Camas is a bulb similar to a daffodil.  After it finishes flowering it begins to senesce.   Senescence (from the Latin word “senēscere”: to grow weak, become exhausted, and to be in a decline).  Once plants senesce after flowering, stop watering so seeds form and bulbs cure.  You should also remove/deadhead the flower stalk.  It should return year after year.
     Camas tolerates light shade but grows best with 8 or more hours of sunlight daily. Camas thrives in temperate climates with 40 or more inches of precipitation (rain and snow). Irrigate 1 inch weekly, as needed, until flowers begin to fade. 
     There are several pest of camas. Camas is favored as forage by deer, so fencing or repellents may be useful, particularly during the first growing season. Bulb predation by pocket gophers can be a substantial threat to stands if left unchecked. For ornamental use, it may be necessary to bury bulbs with a protective wire mesh to prevent herbivory by voles and pocket gophers. The mesh needs to be coarse enough to allow shoots to grow through.
     I hope that you find this information useful and as always Happy Gardening.
