Ryegrass ( Lolium perenne )
Height : 14cm to 58cm included
Origin : Europe, Western Asia, Northern Africa
Environment : Grasslands
Climate : temperate
Ryegrasses exist in both annual and perennial varieties. The perennial species such as Lolium perenne are most suited to live in cool climates as they remain green the whole year. It's thick dense growth makes it ideal both for decorative gardens and for sports (golf courses), but it's also widely cultivated as pasture and
forage plant. Unfortunately, it's also one of the most aggressive graminaceae to allergy-affected people. Ryegrass is the principal grazing grass in New Zealand where some 10 million kilograms of certified seed are produced every year.
