Bentgrass
Agrostis (bent or bentgrass) is a large and very nearly cosmopolitan genus of plants in the grass family, found in nearly all the countries in the world. Bentgrasses are distributed in temperate and cool parts of the world and at high altitudes in subtropical and tropical areas; at least 40 species are found in North America. Some are grown as forage and turf plants, and a number are considered weeds and invasive species in areas outside their native range.
