Pacific bent grass is a tufted perennial grass growing up to 65 centimeters tall. The inflorescence is a panicle of wispy strands, each with several tiny, fuzzy spikelets at the end. The spikelets are two or three millimeters long.

In Australia it is a fire hazard,[2][3][4] and interferes with trains.[5][6]

Agrostis avenacea is known elsewhere as an introduced species and sometimes a noxious weed. It is particularly invasive in California, where it is a weed of sensitive vernal pool ecosystems around San Diego.[7]
