Ecology & Habitat

Habitat

This indian-paintbrush grows in low swales and depressions of open sagebrush or sagebrush flats within coniferous forests at elevations from 3400 to 4900 feet (1050 to 1500 meters). Soils are heavy silt with low rock content. Plants are often found growing in and probably parasitic to sagebrush plants. Three different sagebrush have been reported growing with this Castilleja: Artemisia rigida, A. tridentata, A. ludoviciana
