Sweetgum is a medium to large deciduous tree that must be planted with room to grow. The star-shaped leaves have 5 to 7 pointed, finely-toothed lobes. Yellow-green flowers appear in clusters in April and May. The female flowers develop the "gumballs." The spiny, ball-like fruit contains seeds and can be a nuisance. It has very showy yellow, orange, red, and purple fall foliage. Bark, especially on the branches, is covered in corky projections. It is resistant to drought, compacted soils, deer, and rabbits.
