Discussion

Lupinus nanus is a highly variable complex. Plants in northern California and southwestern Oregon, referred to as L. vallicola, have smaller flowers and may be confused with L. bicolor.

Lupinus nanus occurs throughout California except in the Great Basin and desert regions and northward to Washington.
