Castilleja occidentalis


Castilleja occidentalis is a member of the genus Castilleja, commonly referred to as western Indian paintbrush. Like other members, it is a hemi-parasite.

Distribution

This species has a wide distribution, from the Rocky Mountains north to BC, Alberta and Montana and south to Utah and New Mexico

Habitat

The western paintbrush occurs in areas above and below the treeline. It is found in dry places, favoring rocky soils and talus slopes. It has thin, lanceolate leaves borne on woody stems. The bracts are pale yellow to nearly white. Along with the plants' habitat, this coloration aids identification.
However, this paintbrush often occurs in fragile wet meadows, where it is vulnerable to trampling. Further, coloration can vary to red and purple with all colors between.

Associated plants

The western paintbrush is often associated with tufted hairgrass, golden avens, and Bellard kobresia
