Sycamore - Platanus occidentalis
Sycamores can grow to be very large trees with massive trunks. They form a broad crown. They are highly regarded as shade trees. Audubon Field Guide to Trees of the Eastern Region
Called Buttonwood or American planetree, the wood is used for furniture, butcher blocks and flooring. PA DCNR
"In pioneer times, sycamore's toughness made it a favorite for wheels to pull ox carts and for barber poles and wooden washing machines. It rolled along the rails as panels for Pullman cars and slats for Saratoga trunks; it built stereoscopes that helped people see faraway places; and it brought music home in piano and organ cases and phonograph boxes." American Forests
"Found in river floodplains and in bottomland forests. Will grow in soils that flood. These are important trees along riverbanks, as their roots help provide stable stream banks. Because of their height, they provide nesting sites for great blue herons, wood ducks, and many woodpeckers. The huge leaves provide shade in the summer that cools the water for fish and are important in the food chain for aquatic life. They are fast growing and long-lived and grow well in areas with seasonal flooding." Riverside Park
The seeds of the tree are formed in tight balls which hang from slender stems. They help to distinguish this tree from maples which have a similarly shaped leaf. But the bark should be the real clue to tell them apart.
Native Americans used sycamore for a wide variety of medicinal purposes, from treatment of coughs and respiratory distress to dietary and gastrointestinal aids. Campus Botany Tour
The hollow trunks of old trees are sometimes homes to chimney swifts. Animals also use the dense thickets of these trees for shelter and as nesting sites to raise their young.
It is also a host plant for the Tiger Swallowtail butterfly.
