It grows in many types of habitat, from grassland to the alpine climates of high mountains, in rocky and sandy areas. It is a dominant plant in many types of prairie on the Great Plains, especially shortgrass prairie, where it grows alongside dominant grasses.[2] It grows in windy, exposed, snow-free rock outcrops on mountain peaks in several ranges, including the Cascade Range and the Front Range of the Rocky Mountains.[2] It is most common on dry soils in open areas, tolerating desiccation relatively easily.[2]
This lycophyte forms mats or cushions of creeping stems which fork into small, upright branches. The green, linear or lance-shaped leaves are up to 5 millimeters long including the short, soft bristles on the tips. They are flattened to the stem. The strobili at the ends of the stems can be up to 3 or 4 centimeters long.
This compact groundcover plant protects the soil from erosion and can be used in landscaping for that purpose.[2]
