AC Killarney Orchardgrass

Orchardgrass is a vigorous, medium-to long-lived perennial bunch grass with deep fibrous roots. Orchardgrass prefers soil with good drainage and high fertility for optimum production. It is ideally suited to mix with alfalfa and other legumes in pasture or hay/haylage/silage blends. Orchardgrass is highly palatable and recovers quickly after cutting or grazing. Orchardgrass establishes quickly and begins growth early in the spring, but it is susceptible to overgrazing which may greatly shorten stand life. Bred in western Canada for the harsh Canadian environment AC® Killarney’s unique selection process brings a new level of persistence, productivity, and winter hardiness to Canadian hay and pasture stands.
