Agrostis exarata is a species of grass known by the common names spike bentgrass,[2] spike bent,[3] Pacific bentgrass, and spike redtop. It is native to western North America from Texas[2] to the Aleutian Islands.

Description

This is a common perennial grass reaching one to three feet in height with long, thin, flat leaves each with a ligule of 2–4 millimetres (0.079–0.157 in).

The tuft inflorescence may be up to 30 centimetres (12 in) long and is usually dense with tiny spikelets.[4] It reproduces mainly by seed, but it can also spread via rhizome. This bunchgrass occurs in many plant communities in varied climates. It is considered good forage for livestock.
