Exclamation London Planetree is a hardy and adaptable shade tree that has a pyramidal growth habit. It is not bothered by anthracnose or mildew like sycamores are, and can tolerate urban air pollution. Large, leathery leaves are palmate and turn yellow in the fall. Seeds are in ball-like clusters and hang on into the winter. Exfoliating bark is brown mottled with white when young. A very good shade tree, it is an introduction from Chicagoland Grows.
