What is the common name of Platanus x acerifolia?

Platanus x acerifolia is commonly known as the London Planetree. This tree is a hybrid between the American sycamore (Platanus occidentalis) and the Oriental plane (Platanus orientalis). It is well-regarded for its urban tolerance, making it a popular choice in city landscapes due to its ability to withstand pollution and compacted soils. The London Planetree is characterized by its distinctive bark, which peels away in patches to reveal a lighter inner bark, as well as its large, maple-like leaves and round seed balls that develop in clusters.

The other names listed are associated with entirely different species. Kwanzan Cherry is a flowering cherry tree (Prunus serrulata) known for its beautiful pink blossoms; Sourgum refers to the black gum tree (Nyssa sylvatica), which is unrelated; and Sourwood (Oxydendrum arboreum) is a distinct species known for its fragrant flowers and vibrant fall color. These differences highlight why the correct common name associated with Platanus x acerifolia is the London Planetree.
