The pods of the alfalfa plant produce the tiny, kidney-shaped seeds known as alfalfa seeds. Another name for the perennial legume plant alfalfa is lucerne. The small seeds of the alfalfa plant, a perennial legume commonly grown as a cover crop and feed, are botanically known as alfalfa seeds (Medicago sativa). This is because it may yield high-quality hay or forage for animal feed, these nutrient-dense seeds are frequently utilized in agriculture.
