American Sycamore

Arbor walk #60, Treekeeper ID #5449

The Sycamore is regarded as the largest tree native to eastern North America, and was historically prized by Native Americans for the construction of dugout canoes.

The American Sycamore typically reaches heights of 75-100 feet but are known to reach 150 feet plus in their ideal environmental conditions, which include flood plains and stream banks. The Sycamore is easily identified at a distance from its brown outer bark which exfoliates irregularly to reveal a distinctive white inner bark. It is easy to mistake the Sycamore for the Red Maple, so much so that although the Red Maple is the symbol of Canada, depicted on their penny is actually a Sycamore leaf by accident. Crucially, Sycamore’s have alternate leaf arrangement, while the Maple’s leaves are opposite.
