Lolium perenne L.
Perennial ryegrass is the fastest establishing species of all the turfgrasses. It prefers milder climates, but tolerates temperatures down to minus 16 to 18°C without a snow cover. With a snow cover, ryegrass can tolerate even lower temperatures. In temperate regions, perennial ryegrass is a true perennial with a high persistence. It can be used on most soil types, with the exception of very wet land. Perennial ryegrass exists in early, intermediate, and late types in respect to heading and spring growth. Perennial ryegrass has very high wear tolerance.
Establishment: 7 to 10 days
Use alone or with bluegrass for year-round quality and sod strength.
