I had this identified as the Spur Lupine, Lupinus arbustus. The only other possibility I could come up with was a hybrid of the Yellow Bush Lupine, a nonnative in Washington. Fizzie, however, has identified it as a color variety of Bush Lupine. These were photographed near the beach below Fort Worden near Port Townsend, Washington.
