Wikipedia Abstract

Agrostis gigantea, known by its common name Redtop, is a perennial grass of the Agrostis genus. It is native to Europe, but in the cooler areas of North America was widely used as a pasture grass until the 1940s. Although it has largely been replaced by soybeans and more palatable grasses, it still gets some use in poor soils. It was one of the grasses planted in areas disturbed by the Trans-Alaska Pipeline. It generally does well in response to fires, due to survival of rhizomes and seeds.

Infraspecies

Invasive Species

Agrostis gigantea commonly known as redtop, is reported to be weedy or invasive in some states in the USA and provinces in Canada. Native to temperate and tropical Asia, parts of Europe and North Africa, it was introduced for use as turf or lawn grass, as a fodder and forage species or for erosion control and revegetation purposes. Its impacts include displacement of native species in habitats where it is not managed properly.
