(Not Listed or Proposed under the Endangered Species Act)
Castilleja christii is a showy perennial herb about 6-15 inches tall. The inflorescence is yellow to yellow-orange. It is the only Indian paintbrush associated with late-lying moist snowbanks on the summit of Mt. Harrison. Photo by Teresa Prendusi.
The single known Castilleja christii population occupies approximately 200 acres along the gentle slopes and subalpine meadows of the upper elevations of Mt. Harrison. Photo by Teresa Prendusi.
In 2003, the portion of the population not included in the Mount Harrison Research Natural Area (RNA) was designated as the Mount Harrison Botanical Special Interest Area (BSIA). Interpretive education is an integral part of this species’ conservation program. Photo by Teresa Prendusi.
