Perennial Ryegrass (Lolium perenne)
Perennial ryegrass lasts around 5 years which is considerably longer than the higher yielding Italian and westerwolds ryegrasses. It yields around 13t DM per hectare, it is flexible in use because it can be grazed or cut. It may be made into silage, haylage or hay later in the season. Intermediate varieties generally head around the 3rd and 4th week of May.
Perennial ryegrass is the most commonly grown productive grass in the UK, used particularly for livestock grazing and forage. It has been the subject of plant breeding for over 60 years, ensuring there are a wide range of perennial ryegrass varieties available commercially.
