Alfalfa (Medicago sativa), also known as Lucerne, Purple Medick and Trefoil, is a perennial flowering plant cultivated as an important forage crop.
Alfalfa lives from five to twelve years, depending on variety and climate. It is a cool season perennial legume, growing to a height of 1 meter. It resembles clover with clusters of small purple flowers. It also has a deep root system sometimes stretching to 4.5 metres. This makes it very resilient, especially to droughts. It has a tetraploid genome.
Alfalfa is native to Iran, where it was probably domesticated during the Bronze Age to feed horses being brought from Central Asia. It came to Greece around 490 B.C. being used as a horse feed for Persian army. It was introduced from Chile to the United States around 1860. It is widely grown throughout the world as forage for cattle, and is most often harvested as hay. Alfalfa has the highest feeding value of all common hay crops, being used less frequently as pasture. Like other legumes, its root nodules contain bacteria, like Rhizobium, with the ability to fix nitrogen, producing a high-protein feed regardless of available nitrogen in the soil.
Its wide cultivation beginning in the seventeenth century was an important advance in European agriculture. Its symbiotic relationship with nitrogen-fixing bacteria and use as animal feed greatly improved agricultural efficiency. When grown on soils where it is well-adapted, alfalfa is the highest yielding forage plant.
Alfalfa is one of the few plants that exhibit autotoxicity. Alfalfa seed will not grow in existing stands of alfalfa because of this. Therefore, alfalfa fields must be cleared or rotated before reseeding.
Alfalfa sprouts are used as a salad ingredient in the United States and Australia. Tender shoots are eaten in some places as a leaf vegetable. Human consumption of older plant parts is limited primarily by very high fiber content. Alfalfa has the potential to be the most prolific of all leaf vegetable crops, processed by drying and grinding into powder, or by pulping to extract leaf concentrate [1].
Alfalfa is believed to be a galactagogue.
In the United States, the leading Alfalfa growing states are Wisconsin and California, with most of the latter state's production occurring in the Mojave Desert by means of irrigation provided by the California Aqueduct.

A grass like thing, I have seen it used in Mediterranean cuisine in 'pockets' or as a side dish / salad. It tastes good, but it is said to carry disease-causing micro-organisms and needs to be washed thoroughly

I'm not so sure it's a grain. I thought it was an herb. It's supposed to be really good for you.... particularly your digestive system.
