The London plane tree was cherished by Robert Moses, NYC Parks Commissioner from 1934 to 1960. It is thought that the Parks Department's distinctive logo is based on the leaf of a London plane. The London plane is a hybrid between the native American sycamore and the non-native oriental plane tree. The London plane was planted throughout Central Park from the north side of the Harlem Meer down the East Drive. Recently, London plane trees have been planted in Grand Army Plaza, replicating a historical design that included two rows of this beautiful tree.
