Christ’s Indian paintbrush (Castilleja christii) is a perennial forb 6 to 20 inches tall, and is a striking yellow-to-yellow-orange color. The plant grows best in moist, subalpine meadows. It reproduces by seed, and plant growth begins around snowmelt, leading to peak flowering from July to mid-September. Only one population of this plant is known to exist in the world. This single population occurs on Mount Harrison, a gently sloping mountain-top at the north end of the Albion Mountains in south central Idaho (managed by the Sawtooth National Forest). The species is currently threatened primarily by smooth brome (Bromus inermis), an invasive grass species that is found within the population. The Forest Service and the U. S. Fish and Wildlife entered into a 10-year agreement in 2005 to work together on the conservation of this species.
