Cliff paintbrush (Castilleja rupicola) COSEWIC assessment and status report: chapter 11

Special significance of the species

Populations of Castilleja rupicola in British Columbia are unique in that they are at the northern extent of their geographic range. This species is globally rare and has a relatively small range with less than 100 populations (NatureServe 2003).

The species has no commercial value and is not known in cultivation. It is not known to have cultural, medicinal or spiritual uses. Although no information on this species was found in a major ethnobotany database (http://herb.umd.umich.edu/), other species of Castilleja are used extensively by Aboriginal peoples in North America.
