Castilleja linariifolia is a perennial plant, native to the United States and is the state flowerofWyoming. It has a number of common names including Wyoming Indian paintbrush, narrow-leaved Indian paintbrush, desert paintbrush, Wyoming desert paintbrush, Wyoming paintbrush, linaria-leaved Indian Paintbrush, and Indian paintbrush.[2]
It is a perennial herb.[3] It grows up to one meter in height and has sparse, linear leaves which are between 20 and 80 mm in length and have up to 3 lobes.[4] The flowers, which consist of a pinkish-red to yellow calyx and yellow-green floral tube, appear in panicles or spikes between June and September in its native range.[4]
This species occurs on rocky slopes and arid plains and is associated with sagebrush scrub as well as pinyon pineorjuniper woodland.[4] It is native to Arizona, California, Colorado, Idaho, Montana, New Mexico, Nevada, Oregon, Utah and Wyoming.[5]
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.[2]
The State of Wyoming officially adopted the Indian paintbrush ("Castilleja linariaefolia") as the state flower of Wyoming on January 31, 1917.[2][6]
