Alfalfa

Alfalfa;( Medicago sativa) is a perennial flowering plant in the pea family Fabaceae cultivated as an important forage crop in the US, Canada, Argentina, France, Australia, the Middle East, South Africa, and many other countries. The English name is adopted from the Spanish, originally alfalfez, which in turn is derived from the Arabic al-fisfisa "fresh fodder". The Spanish name is widely used, particularly in the US but it is also known as lucerne in the UK, Australia, South Africa and New Zealand, erba medica in Italy, meaning medical herb, luzerne in France, and lucerne grass in South Asian English. It superficially resembles clover, with clusters of small purple flowers followed by fruits spiralled in 2 to 3 turns containing 10-20 seeds. Alfalfa has been cultivated by humans since at least the 4th century CE and has some use in herbal medicine.

Alfalfa is a perennial forage legume which normally lives 4–8 years, but can live more than twenty years, depending on variety and climate. The plant grows to a height of up to 1 meter (3 ft), and has a deep root system, sometimes stretching more than 15 meters (49 ft). This makes it very resilient, especially to droughts. It has a tetraploid genome.

Alfalfa is a small seeded crop, and has a slowly-growing seedling, but after several months of establishment, forms a tough 'crown' at the top of the root system. This crown contains many shoot buds that enables alfalfa to re-grow many times after being grazed or harvested.

This plant exhibits autotoxicity, which means it is difficult for alfalfa seed to grow in existing stands of alfalfa. Therefore, it is recommended that alfalfa fields be rotated with other species (for example, corn or wheat) before reseeding.
