About This Tree
A medium to large deciduous tree with a straight trunk and a pyramidal to rounded crown that becomes more open and spreading with age. It features glossy, star-shaped leaves, unique winged twigs in some specimens, and numerous spiky spherical fruit clusters that are clearly visible hanging in the canopy.
Leaf Characteristics
Simple, alternate leaves with 5 to 7 deeply palmate lobes, resembling a star. They are medium to dark green in summer, measuring 3 to 7 inches across, with finely serrated margins and turning brilliant shades of red, orange, purple, and yellow in the fall.
Bark Characteristics
Grayish-brown bark that becomes deeply furrowed with ridges and scaly plates as the tree matures. Young branches often exhibit distinctive corky ridges or wings.
Growing Information
Origin Region
Native to the southeastern United States, Mexico, and Central America, well-adapted across eastern North America and widely planted in urban landscapes globally.
Growing Season
Leafs out in mid-spring, produces inconspicuous flowers in spring, develops spiky galls (fruits) through summer that persist into winter, turns vibrant shades of red, purple, and yellow in autumn, and drops leaves for winter dormancy.
Sunlight & Water Needs
Requires full sun for best growth and optimal fall coloration. Prefers moist, deep, well-drained soils but adapts to clay and occasional flooding, with moderate drought tolerance once established.
Mature Size
Reaches a mature height of 60 to 75 feet with a spread of 40 to 50 feet, growing at a medium rate, with a lifespan of 150 years or more.
Special Characteristics
Renowned for its spectacular autumn foliage colors and unique spiky fruit pods (often called galls or sweetgum balls). It tolerates urban pollution and wet soil conditions well, though the fallen fruit can require cleanup in manicured lawns.
Wildlife & Ecology
Provides food for various songbirds, wild turkeys, and small mammals that consume the seeds within the spiky fruit capsules. The dense canopy offers nesting sites and cover for wildlife.
