Double Diamond

Common Name
Tetraploid Annual Ryegrass
Lolium multiflorum

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 establish-ment, excellent leaf to stem ratio, and high forage quality, Double Diamond is an excellent choice for your forage needs.

If overseeding warm-season pastures, mow or graze warm-season grasses short before planting annual ryegrass to aid in establishment.
