Bluebunch wheatgrass is a usually tufted, perennial
grass growing 1 to 4 feet tall. Its green flowers are small and inconspicuous having recurved hairs (awns), and arranged along long spikes. The flowers are primarily wind-pollinated.
Bluebunch wheatgrass grows on plains, gentle and steep slopes, dry mountain slopes, thin rocky sites, and canyons, and in dry, open woods. Although it prefers medium to coarse textured soils, it grows on a variety of soil types. It is tolerant of drought, and cold, and moderately tolerant of shade, but is intolerant of poor drainage, high water tables, and extended inundation.
