Common statewide in North Carolina (though less widespread in the mountains). Although Sweetgum commonly grows in disturbed areas such as old fields and roadsides, it reaches its grandeur in bottomlands, flood plains, and other similar moist habitats where it can grow to 6 feet in diameter at breast height!

Leaves are distinctively palmately lobed and nearly star-shaped. Recent taxonomic studies have resulted in splitting this genus out of the traditional Hamamalidaceae and into the Altingiaceae.

Twigs are often (but not always) adorned with corky wings. Sweetgum gets its common name from the fact that its sap used to be harvested as a source of chewing gum.

In upland old fields Sweetgum is often a weedy, "pioneer" species, meaning it's one of the first tree species to become established in this area following a disturbance (like a fire, clearcut, hurricane, etc.). This is a pine forest that was thinned and burned a year before taking the photo. One year later, the understory is mostly sweetgum saplings.
