Agrostis avenacea is a species of grass known by the common names Pacific bent grass, New Zealand wind grass, fairy grass,[1][2] or blown-grass.[1] It is native to Australia, New Zealand, and other Pacific Islands including New Guinea and Easter Island.
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]
