Wikipedia Abstract

Agrostis capillaris (Common Bent, Colonial bent, Browntop) is a rhizomatous and stoloniferous perennial in the grass family (Poaceae). It is native to Eurasia and has been widely introduced in many parts of the world. Colonial bent grows in moist grasslands and open meadows, and can also be found in agricultural areas, roadsides, and invading disturbed areas. The name agrostis comes from the Greek word meaning forage plant, agros meaning 'a field'.

Invasive Species

Agrostis capillaris is a perennial grass that inhabits various environments ranging from urban to coastal wetland, including grassland as well as near arctic regions of the world. In areas of invasion A. capillaris reduces native biodiversity through disease transmission and competition. The many valuable uses of Agrostis capillaris have resulted in its widespread introduction into many non-native ranges around the world.
