Lolium multiflorum

Lolium multiflorum (Italian rye-grass, annual ryegrass) is a ryegrass native to temperate Europe, though its precise native range is unknown.

It is a herbaceous annual, biennial, or perennial grass that is grown for silage, and as a cover crop. It is also grown as an ornamental grass. It readily naturalizes in temperate climates, and can become a noxious weed in agricultural areas and an invasive species in native habitats.
