Perennial Ryegrass (Lolium perenne)

Cool Season Perennial

Perennial Ryegrass is a short lived perennial bunchgrass. It is similar to Italian Ryegrass in appearance but not quite as aggressive growth. The root system is shallow and dense, leaving it with a low rating to drought tolerance. Salinity tolerance is also low. Perennial ryegrass is easy to establish, but rarely overwinters in most of the prairies. Like Italian, it will tolerate a fair amount of moisture. Regrowth is fast, making it a good grazing grass.
