Peanuts

Arachis hypogaea

Peanuts, also known as groundnuts, are legumes that grow underground. They are characterized by their bushy growth habit and produce edible seeds that are high in protein and healthy fats. Peanuts are widely used in cooking, snacks, and oil production, and they play a significant role in crop rotation due to their nitrogen-fixing ability.
