Shellbark Hickory is a large native deciduous tree with a narrow rounded crown and exfoliating bark that develops sheets as it ages. The dark green compound leaves turn yellow to golden-brown in fall. Non-showy gendered spring catkins can give way to sweet husked nuts, but only starts producing after 10-20 years of age. Grows best in f ull sun and rich, moist well-drained soils.
Carya laciniosa is a host plant for the Hickory Horned Devil.
