It grows up to 1 meter in height and has linear leaves which are between 20 and 80 mm in length and have up to 3 lobes.[2] The flowers, which consist of a red to yellow calyx and yellow-green floral tube, appear in panicles or spikes between June and September in its native range.[2]

This species occurs on rocky slopes and arid plains and is associated with sagebrush scrub as well as pinyon pine or juniper woodland.[2] It is native to Arizona, California, Colorado, Idaho, Montana, New Mexico, Nevada, Oregon, Utah and Wyoming.[3]

State flower[edit]

When options were being considered for a state flower for Wyoming, Dr. Grace Raymond Hebard from the University of Wyoming promoted this species over rival candidates including the columbine and fringed gentian.[1]

The State of Wyoming officially adopted the Indian paintbrush ("Castilleja linariaefolia") as the state flower of Wyoming on January 31, 1917.[1][4]
