Bear-grass is an herbaceous perennial that grows in clumps of basal leaves reaching 1.5 m tall. The leaves are grass-like, but tough and evergreen, with fine teeth on the margins. The stems bear much shorter, bract-like leaves. The tiny white flowers are borne in showy terminal clusters. Bear-grass is common in clearings, meadows, and open to fairly dense forest from low to subalpine elevations. It is in leaf all year, in flower from July to August.
The plant prefers light (sandy) and medium (loamy) soils and requires well-drained soil. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It requires moist soil. Found on dry sunny hills, open wounds, moist places in open woods and clearings in Western North America.
Value for Wildlife:
Bear grass flower stalks are a delicacy for deer and elk and are eaten by other big game animals as well. Bear grass foliage is of low forage value. Elk eat bear grass during early summer in Montana. Thick mats of bear grass and sedge (Carex spp.) provide excellent feeding sites for pocket gophers and other rodents which attract raptors. Sometimes grizzly bears use bear grass leaves as nesting material in their winter dens. (Source)
