Peanut plants are annual herbaceous plants growing 30-50 cm tall, with pinnate leaves and yellowish-orange flowers. Unlike most plants, peanut fruits develop underground after fertilization through a unique process called geocarpy, where flower stalks elongate and push into the soil for seed pod development. Peanut pods typically contain one to four seeds enclosed in a thin, papery shell. Peanuts are popularly eaten raw, roasted, boiled, or processed into products like peanut butter and oil.
