Overview
Alfalfa (Medicago sativa) is a perennial herb that reaches up to 1 meter in height and thrives in light, medium, or heavy soils with a pH range of 6 to 8.5. Native to regions including Algeria, East European Russia, France, Iran, Iraq, Italy, Kazakhstan, Kirgizstan, and other parts of Central Asia, this plant is widely cultivated for its edible leaves, shoots, and seeds. Known for its light and airy nature, alfalfa is often grown in areas with a hardiness zone between 4 and 8. Its distinctive feature lies in its ability to fix nitrogen from the air into the soil, benefiting other plants while also serving as an important forage crop.
