Peanut

Peanut

Arachis hypogaea

The peanut is an annual herbaceous plant that grows 30 to 50 cm (1 to 1.6 ft) tall. It is unusual because it flowers above ground, but fruits below ground. The flowers are typically yellow-orange. After pollination, the flower stalk elongates and bends downward, pushing the developing ovary into the soil. The peanut pod then matures underground. While technically a legume, it's often considered a nut in culinary contexts. It is primarily grown outdoors for commercial and personal food production.
