Alfalfa is widely recognized as the most important pasture and
hay plant in North America and for good reason. Alfalfa is a
perennial, nutrient-rich legume capable of extending its roots
more than 50 feet into the soil. This makes the plant very
resistant to drought, but most importantly provides it with
ready access to the minerals existing deep underground.
Originally from the Middle East, alfalfa was introduced to the
United States by Spanish colonists. The plant grows to a height
of about three feet above the surface and can live for more than
twenty years. Alfalfa is grown extensively around the world,
especially in Argentina, Europe, and Asia. In Britain,
Australia, South Africa, New Zealand and south Asia, it is also
known as lucerne. Alfalfa is widely adapted to temperate and
subtropical climates and soils, but is not well adapted to humid
conditions. It's not picky about its soil, but alfalfa prefers
plenty of sun and water. Alfalfa is primarily reproduced by
cross-fertilization effected by bees. Alf
