American Sycamore. Native to rich, moist soils of Eastern North America, the American sycamore (Platanus occidentalis) is also called American plane tree, buttonball or buttonwood. It generally grows to 100 feet tall, but can reach 150 to 170 feet high.
Another possibility is that the sycamore discards its outer bark as a protective measure again invasions by parasites, fungi, mosses and lichens. Whereas most plants depend on their leaves for photosynthesis, or the process of using the sun's energy to manufacture food, sycamores do not need leaves for this purpose.
