Lupines?

The Quest: Mystery Wildflower

As my husband and I crossed the mountains separating the flat agricultural land of the San Joaquin Valley of California and the Mojave Desert, we came across Bear Mountain. All sorts of wildflowers brightly colored the hills along the road. We stopped to photograph a lovely bluish purple flower in particular. In my childhood, blue was my favorite color, and I always wanted to see a blue flower. These almost qualify.

The habitat was grassland, a cattle ranch, I believe. The altitude was perhaps around 2000 or 3000 feet. The location was Tehachapi, CA, amidst a range of mountains separating the agricultural lands of California from the Mojave Desert.

Please send me an email with any thoughts on the identification of this lovely wildflower or any great pieces of information about its life habits, its traditional uses, and its symbolism. Is this a type of lupine? Thank you so much for any help you can provide.
