Hackberry

Celtis occidentalis, commonly known as the Common hackberry, is a medium-size deciduous tree native to North America. It is also known as the nettletree, beaverwood, northern hackberry, and American hackberry. It is a moderately long-lived hardwood with a light-colored wood, yellowish gray to light brown with yellow streaks.
The Common Hackberry is easily distinguished from elms and some other hackberries by its cork-like bark with wart-like protuberances. The leaves are distinctly asymmetrical and coarse-textured. It produces small berries that turn orange-red to dark purple in the Autumn, often staying on the trees for several months. The Common Hackberry is easily confused with the sugarberry (Celtis laevigata) and is most easily distinguished by range and habitat. The Common Hackberry also has wider leaves that are coarser above than the sugarberry.
