Highlights
Sweetgum (Liquidambar styraciflua) has star-shaped leaves that turn every fall color at once. Chicago Botanic Garden describes trees turning shades of red, purple, yellow, and orange all on the same tree, and it’s true: one branch can look like a box of crayons.
It also drops gumballs. Lots of them. The spiky seed balls are why some people curse this tree, and why goldfinches love it. Plant it where the balls can fall on mulch or lawn edge, not on a patio, and you get one of the most colorful big shade trees in the East.
Is sweetgum a good choice for my yard?
Yes, if…
- You want a big shade tree with real fall color. It grows 60 to 75 feet tall and 35 to 50 feet wide.
- You have damp or clay soil. It handles wet soils and compacted ground, and Penn State lists it as a rain garden tree.
- You want to feed winter birds. Goldfinches eat the seeds during the winter.
- You want giant silk moths. Luna, imperial and regal moth caterpillars all feed on it.
Skip it if…
- It would hang over a patio, driveway or sidewalk. The gumballs are a litter problem, they roll underfoot, and the tree can form large surface roots.
- You have a small yard. This is a big tree, and it gets there fairly fast.
- Your soil is alkaline. UF says to plant it only in soil with a pH of 7 or less; in high-pH soil the leaves turn yellow.
- You garden in zone 4 or colder. It’s hardy in zones 5 to 9, and marginal at the cold end.
Why sweetgum matters
Sweetgum is a seed tree for winter. The gumballs ripen from September to November and hang on through much of the winter, and birds, squirrels and chipmunks work them over the whole time. Ohio’s state nursery says the seeds feed goldfinches, chickadees, and mourning doves through winter.
It’s also a nursery for some of the biggest moths in North America. In the Southeast, luna moth caterpillars feed mainly on sweet gum, hickory, walnut and persimmon. The regal moth’s caterpillar, the hickory horned devil, eats sweetgum too, and so do imperial moths.
How does one tree get so many colors?
Yellow and orange pigments are in the leaves all summer, hidden under the green. In fall, as the green fades, they show through. Red and purple are new: sugars trapped in the leaves change chemically into anthocyanins, and sunny fall days make more of them. Each leaf runs its own mix, which is why one sweetgum can wear the whole palette.
Where sweetgum shines in your yard
- A shade tree for a big lawn, far from the patio.
- A damp low spot or the edge of a rain garden.
- A wildlife corner where the gumballs can fall into mulch and stay there.
- A fall color anchor seen from a window.
- A street tree on a wide tree lawn, where UF recommends more than 6 feet of soil width.
- A woodland edge with understory shrubs below.

Beginner tip
Rake gumballs into the beds instead of bagging them. They break down slowly, and the spikes make the mulch less inviting for digging squirrels and cats.
How to grow sweetgum
When to plant
Spring. The Lady Bird Johnson Wildflower Center says the roots take 3-4 months to recover from transplanting, so give them a full growing season before winter. Cornell notes it’s difficult to transplant bare root, so start with a container or balled tree.
Sun and soil
Full sun is best; it handles part shade. It grows best in rich, moist soil, clay included, and acidic to neutral pH. Once settled, its drought tolerance is moderate.
Where to put it
Plant it at least 15 feet from paving and away from where people walk barefoot. Under the canopy, a wide mulch bed or a planting of shade-tolerant groundcover hides the gumballs better than lawn does.
Fewer gumballs
If the fruit is a deal breaker, look for ‘Rotundiloba’, which is fruitless but only hardy to zone 6. ‘Slender Silhouette’ is a very narrow tree sold as fruitless, though Purdue notes it still makes a small number of gumballs. Keep in mind that no fruit also means no seeds for the goldfinches.

Where is sweetgum native?
Native to 26 US states and Washington, D.C.

What are good pairings for sweetgum?
Mt. Cuba Center suggests fothergilla as an understory companion. Other natives that like the same moist, acidic soil: fothergilla, Virginia sweetspire, winterberry, spicebush and, in the shade below, Christmas fern.
Where can I buy sweetgum?
Sweetgum is easy to find at native nurseries and many regular garden centers. Fruitless cultivars are more common at larger nurseries. Start with our list of native plant nurseries or order online.
FAQs
How do I stop sweetgum balls?
Plant a fruitless cultivar, or plant the tree where the balls don’t matter. ‘Rotundiloba’ is fruitless. There’s no reliable way to stop an existing tree from fruiting, so put it where gumballs land on mulch.
How fast does sweetgum grow?
Moderately fast. The Forest Service calls it a moderate to rapidly growing tree, and seedlings on good sites can grow 2 feet in their first year.
Do birds eat sweetgum balls?
Yes, the seeds inside. Goldfinches are the regulars, and the Forest Service lists birds, squirrels, and chipmunks as seed eaters. Watch a tree in January and you’ll see finches hanging upside down on the balls.
Is sweetgum deer resistant?
Moderately. NC State calls it moderately resistant to deer. Rutgers rates it “occasionally severely damaged,” and the Forest Service notes light to moderate winter browsing, so protect young trees.
Will sweetgum roots damage my sidewalk?
They can. UF says it can form large surface roots. Give it a wide planting area and keep it away from paving.
What’s the difference between sweetgum and a maple?
Check how the leaves attach. Sweetgum leaves alternate along the twig; maple leaves come in opposite pairs. Sweetgum leaves are also glossy and star-shaped, and crushed, they smell resinous.
Plant nerd fact
Gum, the original kind
Sweetgum is named for its sweet balsamic sap, which hardens into a fragrant gum where the bark is cut. The Cherokee and Choctaw chewed the hardened resin, and a Spanish conquistador wrote about seeing the Aztec emperor enjoying a resinous stick from the tree.
Chemists still find it useful. In 2008, researchers reported a way to pull 2.4 to 3.7 percent pure shikimic acid out of sweetgum seed balls. That compound is the starting material for oseltamivir, the flu drug sold as Tamiflu.
Sweetgum asks for one thing: room. Give it a spot where the gumballs can fall without bothering anyone, and it pays you back every October and feeds the finches all winter. For a smaller tree with big fall color, see fothergilla or our native dogwoods. Happy planting!
