Hackberry (Celtis occidentalis) is among the rare trees that survives harsh urban growing conditions, and looks good doing it. This airy, graceful tree performs beautifully urban settings. Elm-like in character, it has similar arching branch structure and foliage. It’s a broad-topped tree at maturity, about 40 feet tall and 30 feet wide. Foliage is light green and turns yellow in the fall. Tolerant of heat, cold and urban abuse, this deep-rooted tree rarely lifts sidewalks. It is also tolerant of air pollution, salt spray, high pH soils and drought. Its rough, corky bark adds visual interest and resists damage. Birds love the tiny, garden pea size fruits that persist into the winter months, and it is an important source of food for butterflies. Operation ReLeaf will be selling Hackberry (#7 container grown) for $25.00 per tree at Cerro Gordo County, Tama County, And Winneshiek County this fall.
