Castilleja flava
Also called Yellow Paintbrush
Castilleja flava, the yellow paintbrush, is a species of paintbrush flower native to the western United States. It is strongly associated with bushy species of sagebrush.
Yellow paintbrush is native to the Intermountain West from Colorado and Utah northwards. The Natural Resources Conservation Service only records the variety rustica of the species growing in Lincoln County, Washington with no other known populations. Likewise rustica is the only variety found in northeastern Oregon. Both varieties are found in Idaho, but rustica is far more widespread growing throughout central parts of the state and flava in the southeast. Both varieties grow in Montana, but primarily flava and all in the southwestern end of the state. It is found throughout the western two-thirds of Wyoming. In Colorado it grows in the northwest, almost entirely west of the Great Divide except for small numbers to in Jackson County. The species is primarily in eastern counties of Utah as far south as Garfield County, but also in Box Elder County in the northwest. It also is native to the three northern counties of Nevada, Elko, Humboldt, and Washoe. It grows at elevations of 300 to 3,000 meters (980–9,840 ft).
