    Italian Ryegrass Overview

    Lolium multiflorum is a herbaceous annual grass that is grown for silage or as a green manure cover crop. It is also known as Festuca perennis. Native to Asia, Europe and Northern Africa, it has been cultivated and naturalised around the world to help stabilise soils and prevent erosion. However, in fertile soils it can out compete rarer grasses and has spread to waste areas alongside. It can sometimes be mistaken for Lolium perenne (Perennial Ryegrass) and Elymus repens (Couch grass), Italian Ryegrass is identifiable as it has a rounded stem and the spikelets have a long bristle at the top.
