Read the Latin on the tag. Dark crimson fall color is L. styraciflua ‘Lane Roberts’. [1] Long, finger-like lobes and orange-yellow fall are L. styraciflua ‘Worplesdon’. [2] Both still fruit. The species baseline is L. styraciflua, with more variable fall color from seed. [3]

What is the difference between Lane Roberts and Worplesdon?

Lane Roberts is grown for deep crimson fall color. Worplesdon has narrower, finger-like lobes and orange-yellow fall. Both can set gum balls.

Not maple, and not fruitless Rotundiloba

Maple leaves sit opposite on the twig and the fruit is a winged pair, not a spiky ball. Sweetgum leaves are alternate, with five to seven pointed lobes. Formosan or Chinese sweetgum (Liquidambar formosana) is a different species. Fruitless ‘Rotundiloba’ is a rounded-lobe tag other shops sell, and it still has aggressive roots. [4]

Is sweetgum a maple?

No. The star leaf looks related, but maple is Acer with opposite leaves. Sweetgum is Liquidambar with alternate leaves and gum balls.

Is there a fruitless sweetgum?

Yes — ‘Rotundiloba’ is the usual fruitless tag, with rounded leaf lobes. Other shops sell it. Named kinds here still fruit.

If the tag says maple or Rotundiloba, it is a different plant — read the Latin before you site it as these sweetgums.

FAQ

Do you list Rotundiloba?

No. Rotundiloba is a real fruitless tag other shops sell. The two jobs here are named fall-color selections and the species tree.

Do you list Slender Silhouette?

No. Columnar and cold-hardy extras such as Slender Silhouette or Moraine are sold elsewhere. The catalog here is Lane Roberts, Worplesdon, and the species.

Is a gumball tree a sweetgum?

Yes. Gumball tree is a common name for American sweetgum. Confirm Liquidambar styraciflua on the tag.
