RPR® marks the rebirth of a subspecies of grass variety. In the United States, Lolium Perenne Stoloniferum, the subspecies to which RPR® belongs, has not been observed since 1836. RPR® is the first variety of perennial ryegrass growing via determinate stolons to have been officially registered in the US as Lolium Perenne Stoloniferum since that date.
Perennial ryegrass had been used for sports pitches and golf courses for quite some time, but RPR® is an innovative novelty that Barenbrug introduced in the United States in 2010. There, the grass mixture was immediately found to be extremely suitable for sports pitches. In the US, Barenbrug’s RPR® was granted an Innovation Award at the STMA (SportsTurf Managers Association) Show of 2011. In Europe, RPR® was introduced in the Netherlands in 2012. Other countries were soon to follow: Belgium, Germany, Denmark, Sweden, the Czech Republic, Poland, Italy and Rumania. The RPR® grass for sports pitches, golf courses and public green spaces was also nominated for the Gouden Klavertje Vier innovation award of 2013 and the SportFM innovation award of 2015.
