About
Linanthus pungens (syn. Leptodactylon pungens) is a species of flowering plant in the phlox family known by the common names granite prickly-phlox and granite gilia. It is native to western North America from British Columbia to Baja California and east to Montana and New Mexico.
Where it grows
This plant occurs in pine forests, pinyon-juniper woodlands, sagebrush steppe, and grasslands, and their ecotones. It can be found in subalpine and alpine climates. It can be found in mountain passes and high-elevation fell fields and in lower elevation desert washes. It can tolerate a wide range of conditions, from harsh winters on exposed mountain slopes to hot summers in desert valleys. It is more common in dry climates with low levels of precipitation, and it is tolerant of drought. The plant grows in poor, shallow, rocky, sandy, and salty soils, sometimes in thin layers of soil overlying bedrock. It can grow and is common on volcanic soils, such as pumice, lava and andesite. It is a dominant species in some areas, for example, the white pine-mountain hemlock forests and shrublands in El Dorado County, California, and the sagebrush near the U.S. Sheep Experiment Station in eastern Idaho.
