American Sycamore
Platanus occidentalis
This native tree species is one of the largest trees in the eastern United States.They can be quite massive at 98-130 ft. tall and trunk diameters of 5-6 ft. In the wild they are commonly seen along stream beds and wetlands. The leaves are also large, 4-9 inches long, bright yellow green on top and pale underneath. The mottled grey bark of the tree is not very elastic. As the tree grows, it doesn't stretch; and the bark peels off in large chunks. However, in so doing, the unique characteristics of this tree's creamy inner bark are revealed. This gives the tree a startling whiteappearance, particularly in the winter. Thus, the American sycamores have been called the "ghosts of the forest".
