Discussion | Castilleja suksdorfii is endemic to wet habitats in the Cascade Range from the Goat Rocks Wilderness Area in Yakima County, Washington, south to the vicinity of Crater Lake National Park in Klamath County, Oregon. Reports of this species farther north in Washington and southern British Columbia are referable to C. rupicola. Castilleja suksdorfii is a polyploid species and may be of hybrid origin.

Castilleja attenuata is a common and widespread species, ranging from southwestern Canada to northern Baja California, with several disjunct populations in central Chile. It is sensitive to competition from weeds. Disjunct populations in the Rincon Mountains in Pima County, Arizona, often have pink bracts but are otherwise typical.
