Lolium perenne
Double Diamond
Double Diamond tetraploid annual ryegrass is a cross between TAMTBO and Master annual ryegrass. Mature plant height and flag leaf width are incredible. In a private trial in Alabama, the trial managers mentioned that Double Diamond had the widest leaves of any annual ryegrass variety they had seen. Exhibiting high forage yields, very fast establishment, excellent leaf to stem ratio, and high forage quality, Double Diamond is an excellent choice for your forage needs.
