Phenology: Flowering Jun–Oct.
Habitat: Sandy or rocky soils on steep limestone slopes, rocky hillsides, roadsides, dry streambeds.
Elevation: 1200–3400 m.

Distribution

Calif., Idaho, Nev., Utah, Wyo.

Discussion

Subspecies garrettii is a diploid taxon occurring mainly in the Great Basin from northwestern Wyoming (Lincoln, Park, and Teton counties) to southeastern Idaho (Bannock, Bonneville, and Franklin counties); northern Nevada (Eureka County); extensively in montane areas of Utah from the north-central to the southwestern part of the state, with a disjunct locality in the Abajo Mountains in southeastern Utah (San Juan County); and barely to the eastern slope of the Sierra Nevada in California (Inyo County) and scattered in the desert ranges of the Mojave Desert in eastern San Bernardino County. In those areas in California, it overlaps and intergrades with subsp. latifolium.
