Carya glabra - Pignut hickory
Description: Pignut Hickory is a large deciduous tree with yellowish-green leaves turning golden-yellow in the fall. It is monoecious (separate male and female flowers grow on the same tree); the non-showy flowers bloom April-May. The female flowers are followed by nuts, but not until the tree is about 25 years old. The nuts are inside husks, which split open in the fall when ripe; the nuts are a food source for wildlife. Early settlers called this tree Pignut Hickory when they found their hogs would eat the nuts, which are too bitter for human consumption. This tree is a host for butterfly and moth larvae (caterpillars), including Luna Moth (Actias luna), Funerary Dagger (Acronicta funeralis), and Giant Regal (Citheronia regalis). It tolerates both dry and moist soils. Give this large tree plenty of room to grow! Use Pignut Hickory as a tall shade tree in large yards and in parks.
