Pignut

Pignut is a common name used for several plants. The two most widely referenced are the pignut hickory (Carya glabra), a North American tree, and Conopodium majus, a European herbaceous plant also known as earth-nut. The name pignut derives from the edible nuts or tubers these plants produce, which have historically been consumed by people and wildlife.

Pignut hickory (Carya glabra) is a deciduous tree in the walnut family (Juglandaceae) native to eastern North America. It typically grows as a medium to large tree with a straight trunk and an openly spreading crown. Leaves are pinnate with several leaflets. The tree produces edible nuts enclosed in a thick husk; when ripe, the kernel is sweet and is eaten by wildlife and humans. The wood is hard and strong and has been used for tool handles, furniture, and other timber applications.

Conopodium majus, commonly called pignut or earth-nut, is a herbaceous perennial in the carrot family (Apiaceae). It is native to Europe and western Asia and has been introduced elsewhere. The plant forms small underground tubers that resemble peanuts in size and texture. The tubers are edible and have historically been gathered as a food source, especially in times of scarcity. Above-ground parts bear small yellowish-white flowers in umbels.
