Mammoth Orchardgrass (50 lb bags) is an early-medium maturing orchardgrass that was bred for high forage production and successful adaptation to diverse weather conditions. It survives the snowy winters of Alberta, the humid summers and cool winters of Missouri, and the desert-like summers of Northern California. Mammoth is a dormant variety with low winter growth, ensuring its survival in excessively cold winters. One of Mammoth’s major advantages is that it will come back in the fall for one last cutting of hay or an extended period of grazing.
