Platanus x acerifolia
London Plane Tree
Franklin and Marshall College, Buchanan Avenue (by parking lot of North Museum), Lancaster PA
This tree, a hybrid of the Oriental Plane (Platanus orientalis) and the American Sycamore (Platanus occidentalis), is probably at least 150 years old (the age formula puts it closer to 200). Hopefully it will survive the massive campus construction that is currently enveloping it. The photos on this webpage do not do this beautiful tree justice.
This amazing species is one of the most efficient trees in removing small particulate pollutants in urban areas.
