Description

The American Sycamore is one of the most massive and easily recognizable deciduous trees of North American forests. Known for its distinctive exfoliating bark that peels away in large camouflage-like plates to reveal greenish-white inner bark, the tree develops a massive trunk and a wide, spreading canopy. The leaves are characteristically large and maple-like with distinctive jagged margins. In autumn, the foliage transitions to a muted yellow-brown or rich copper before dropping to reveal spherical aggregate fruits known as buttonballs that often persist through the winter.

Habitat

Found primarily along streambanks, river floodplains, lake shores, and moist bottomlands, thriving in deep, rich, moist alluvial soils with full sun exposure

Native Range

Native to the eastern and central United States as well as parts of northeastern Mexico, extending from Maine westward to Nebraska and south to Texas and Florida
