Alfalfa Classed as an Annual or Perennial Alfalfa was introduced into the U.S. from southwest Asia. It is believed that over 3,000 years ago Medicago sativa was first cultivated in, and named for, the ancient country of Media (present northwest Iran). Like other members of the Bean or Pea Family alfalfa fixes Nitrogen with its roots, making it a valuable crop to rotate into fields, since it is a also a very common source of feed for many livestock. In the Phoenix area farmers can get up to 11 cuttings a year. One of the most interesting relationships is the relationship between honeybees and alfalfa. While honeybees will work the alfalfa fields they do not like to do so since they get hit by part of the flower when working the alfalfa blossom. Never the less, contrary to what the government agriculture people say, the honeybee will work alfalfa fields and they will very quickly fill bee hives with honey from alfalfa. A leaf cutter bee has been introduced into agriculture areas to help with alfalfa pollination, but it really is not necessary in my opinion. Here is that story. The alfalfa leafcutting bee was introduced into the United States from western Asia in the late 1930s for the commercial pollination of alfalfa plants. This bee is specially adapted for foraging on alfalfa flowers, which honey bees tend to avoid (if other nectar sources are available)(if not, then bees work alfalfa with eagerness). These small flowers must be pried open by the pollinating insect, which then gets dusted with pollen by the flower's spring-loaded anthers. The alfalfa leafcutting bee is managed intensively for alfalfa pollination in Washington, Oregon, California, Idaho, and Montana. Production of the bees is a multimillion dollar business in the United States and Canada, and it is also important in Russia.
