Hackberry (C. occidentalis) 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.
Hackberry is used as a shade tree or a boulevard tree. 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.
The bark of hackberry provides year-round interest in landscapes. The fruit is a popular food for birds and small mammalian wildlife. Much of the fruit remains on the tree throughout winter until it is eaten by birds.
