This is a perennial bunchgrass growing in upright clumps 60 to 120 centimeters tall. The straw-colored stems have nodes at intervals which are fringed with fluffy hairs. The leaves are 20 to 30 centimeters long and blue-green when new, drying to a reddish yellow. The inflorescence is a feathery array of spikelet units. Each unit is composed of one hairy, tan, fertile spikelet with a twisted awn up to 3.5 centimeters long twinned with a stalked, sterile spikelet which is much smaller and lacks an awn. The long-haired spikelets are wind-dispersed.

In its native range, this grass is useful as a forage for grazing animals and a groundcover for revegetating cleared land.[1] It is very drought resistant. It is considered an indicator of rangeland damage, as it is often one of the first native species to be eliminated when an area is overgrazed.[1]

It is known elsewhere as an introduced species and sometimes a weed, such as in Hawaii.

It is grown as an ornamental plant for its showy inflorescences.
