The Sweetgum tree, with its star-shaped leaves, neatly compact crown, interesting fruit, and twigs with unique corky growths called wings, is an attractive shade tree. It turns brilliant shades of yellow, orange, red and purple in autumn. Its wood is alternatively streaked with reddish-brown and black, making it popular for fine furniture and interior finishing. Sweetgum has become a prized shade tree in parks, campuses and around residences with space for large trees.

American sweetgum seeds are eaten by eastern goldfinches, purple finches, sparrows, mourning doves, northern bobwhites, and wild turkeys. Small mammals such as chipmunks, red squirrels and gray squirrels also enjoy the fruits and seeds.
The Sweetgum tree is native to the southeastern United States and a member of a genus made up of only six species. The others are found only in Asia. The first historical reference to the tree comes from the author and soldier, Don Bernal Diaz del Castillo, who accompanied Cortez in 1519 and was a witness to ceremonies between Cortez and Montezuma, who both partook of a liquid amber extracted from a Sweetgum tree. The tree itself was fist noticed and recorded by the historian Alvar Nunez Cabeza de Vaca in 1542. Once commercially popular for soaps, adhesives and pharmaceuticals, today its wood is valuable for fine furniture and interior finishing.
Requires moist soil conditions, moderate drought tolerance.
The leaves are distinctively star-shaped with five points or lobes, and occasionally seven. They have toothed margins, grow alternately along the twig, and are borne on long petioles. They are medium green in summer and orange, purple, red or yellow in autumn.
Yellow-green in color, not distinctive.
The fruit is long-stemmed, woody and bur-like; approximately 1-1/2 inches in diameter.
Rate of growth refers to the vertical increase in growth unless specified differently. Rate, as is true for size, is influenced by numerous variables such as soil, drainage, water, fertility, light, exposure, ad infinitum. The designation slow means the plant grows 12” or less per year; medium refers to 13 to 24” of growth per year; and fast to 25” or greater.Manual of Woody Landscape Plants, by Michael Dirr.
