Lolium perenne

Perennial ryegrass

Very suitable where shade is a problem

Sport + Lawn: Also with shade!

The French official results ranks Gianna at the top of the list for both sport and lawn use. With very high scores for wear tolerance and density. The visual merit is very high in average, also during winter and summer. DLF R&D trials combining artificial wear and shade (tunnel), identified Gianna as superior to most other varieties. Sure that Gianna will find its way to modern winter game stadions!
