Pecan is a massive native deciduous tree with a spreading rounded crown and exfoliating bark. The compound green leaves turn yellow-brown in fall. Non-showy gendered spring catkins can give way to sweet husked nuts, but only starts producing after 8-10 years of age. Grows best in f ull sun and rich, moist well-drained soils.
Carya illinoinensis is a host plant for the Luna Moth and the Hickory Horned Devil.
