Common hackberry in the landscape

Hackberry is a large native tree found commonly on river terraces and floodplains in southern and central Minnesota. It is related to the American elm and after the arrival of Dutch elm disease in Minnesota, hackberry often replaced American elms both in native forests and in planted landscapes. C. occidentalis transplants easily as a small bare root plant in spring or as a containerized or balled and burlapped plant throughout the growing season. It establishes easily and grows well in urban landscapes because of its wide soil adaptability and its tolerance of heat, drought salt spray, wind, ice, and short-term flooding. One of the few liabilities of this species is the presence of disfiguring witches brooms that can be seen throughout the crown of some trees during winter. Hackberry is used as a shade tree or a boulevard tree. The fruit is a popular food for birds and small mammalian wildlife.

The bark of hackberry provides year-round interest in landscapes. Bark of young trees appears to be covered with bumpy warts. As trees mature, the bark pattern changes to cork-like ridges. Canopies full of 2 1/2 - 4" dark green leaves provide shade in summer. Fall color is yellow. 1/3-1/2" berry-like fruit called drupes can be seen throughout tree canopies during the season as they change from green to purple or reddish brown in autumn. Each drupe contains one hard seed. Much of the fruit remains on the tree throughout winter until it is eaten by birds.
