Sweetgum with Deeply Lobed Leaves: A Potential Cultivar Discovery

When a Sweetgum Doesn't Look Like a Sweetgum

A homeowner in southern Alabama found a tree with sweetgum-like leaves but unusually deep lobes—and no "gumballs" (spiky fruit) underneath. They were convinced it wasn't a sweetgum. The verdict? It is a sweetgum (Liquidambar styraciflua), but an exceptional leaf form.

Why Leaf Shape Varies

Sweetgum leaves are famously variable—even on the same tree. Factors include:

• Sun vs. shade leaves (sun leaves more deeply lobed)
• Juvenile vs. mature growth
• Genetic variation within the species
• Environmental stress responses

Could This Be a New Cultivar?

If the tree combines deep lobes, excellent fall color, and reduced or absent fruit production, it may have ornamental value worth propagating. Fruitless or low-fruit sweetgums are highly desirable for landscape use.

To explore this possibility, the homeowner should document the tree thoroughly (photos of leaves, bark, form, fall color) and contact plant introduction programs like Plant Introductions, Inc. or ItSaulPlants for evaluation.
