American sycamore
Platanus occidentalis
American sycamore leaf underside, photographed in Warren County, North Carolina. Trace the palmately branching veins and angular lobes on a full blade.☀ Full sun · ◐ Part sun or part shadeCathy DeWitt ↗ · CC BY 4.0Photo contextResized and converted to WebP; no diagnostic content altered.
Dramatic native for very large moist sites; litter, anthracnose, and aggressive roots preclude tight spaces.
A large blade has three to five pointed lobes with toothed edges. Check alternate attachment to separate it from maples.
More growing details
Read the bark
Upper bark flakes away to expose pale cream and white patches; old lower trunks can remain rough.
Fruit & seed
Round hanging balls hold many small seeds; American sycamore usually has one ball on each stalk.
Winter character
Pale upper bark and lingering solitary seed balls are strong clues.
Origin & place
The species occurs naturally in the southern Appalachian region; a planted specimen is not evidence of wild local origin.
Compare with London planetree
London planetree often bears paired seed balls; count several stalks and consider planted hybrids.

LOOK CLOSELY
Two views, a closer look.
Place two photographs beside one another. Compare the overall plant with leaves, flowers, or bark when those views are available. Captions identify what each photograph actually shows. Images are not at the same scale; species references may show different cultivars.
