Discussion

Variety exserta is the most common and widespread Castilleja in California. In large masses, it is a showy spectacle in springtime. Pink to purple forms are most common, but color morphs with white bracts are often found intermingled in small numbers. In addition, there are often small differences among populations, especially in corolla color and markings. Early records from Oregon and Washington are either garden plants or waifs, not native populations, and none has persisted.
