The Wild Peanut Flower is a kind of ornamental grass with the botanical name Arachis duranensis, among others, and that blooms bright yellow flowers that strongly resemble those of the Peanut Plant (fig.), hence the name.

The grass however consists of more rounded leaves and it yields a different kind of peanut with a much smoother husk. The plant that yields the peanuts we eat today, i.e. Arachis hypogaea (fig.) is an allotetraploid thought to have derived from hybridization between A. duranensis which has the A genome, and Arachis ipaensis, another diploid that has the B genome, while their chromosomes are exactly the same. Even though this is a wild plant, it is often used in oriental gardens, especially as a ground cover for lawns and at the base of trees.
