Alfalfa (“lucerne” for those “down under”) is leafy forage that is a rich, highly palatable, perennial legume. This type of plant “fixes”atmospheric nitrogen in the root system, converting gaseous nitrogen into plant nitrogen (protein). Like bermuda grass, it is not native to the USA, but likely came in from central Asia and has been known for thousands of years as a superb animal and horse forage. Alfalfa grows almost everywhere in the USA, perhaps best in the mid-south and less so in the upper north.
