Ryegrass (Lolium) is a genus of nine species of tufted grasses, family Poaceae. Also called tares, these plants are native to Europe, Asia and northern Africa, but are widely cultivated and naturalised elsewhere. Ryegrasses are naturally diploid, with 2n = 14, and are closely related to the fescues Festuca.

Ryegrass should not be confused with Rye, which is a grain crop.



The following are accepted as distinct species:

Cultivation and uses

Ryegrasses contain some species which are important grasses for both lawns, notably at The Championships, Wimbledon, and as pasture and hay for livestock, being a highly nutritious stock feed. They are also used in soil erosion control programs. It is the principal grazing grass in New Zealand where some 10 million kilograms of certified seed are produced every year. There is an enormous range of cultivars. The primary species found worldwide and utilized for both lawns and as a forage crop is perennial ryegrass (Lolium perenne). Like many cool-season grasses, it is often infected by a clandestine, fungal endophyte which lives symbiotically within its leaves.

Some species, particularly L. temulentum, are weeds which can have a severe impact on the production of wheat and other crops. Ryegrass pollen is also one of the major causes of hay fever.
