Platanus × acerifolia
London Planetree

Platanus x acerifolia is quite similar to P. occidentalis, but was originally advertised as being much more pest resistant. P. x acerifolia was quickly overplanted, and it is clear that pest resistance varies among hybrids, and can be quite poor. Pests that can severely affect this species include sycamore anthracnose, cankerstain, Botryosphaeria canker, leaf spot, powdery mildew, sycamore lace bug, and American plum borer. One of the largest of shade trees, making massive, majestic specimens. The mottled, multi-colored, exfoliating bark is very beautiful and makes for excellent winter interest. Needs a large volume of soil space. Leaves, twigs, bark, and fruit contribute to a significant litter problem. Although this species can tolerate urban conditions, it is generally not advisable to use as a street tree, due to the continuous litter produced and large space required.
