Hackberry trees (Celtis occidentalis) are tough, fast-growing shade trees valued for their adaptability, resilience, and attractive, rounded canopy. Ideal for USDA Hardiness Zones 3–9, hackberries thrive in a wide range of soil conditions and tolerate drought and wind with ease. These low-maintenance trees feature serrated green leaves that turn yellow in fall, along with small berries that attract birds and wildlife.
