Description
London planetree is a large street tree that looks very much like American sycamore (Platanus occidentalis). This is not surprising since London planetree is the product of hybridization between the American sycamore and the oriental planetree (P. orientalis). London planetree is sometimes sold, mistakenly, under the name, P. orientalis, and often is confused with American sycamore. All three are characterized by thin, flaking bark which gives the trunks an attractive mottled appearance with irregular white, gray, brown and green patches, and by lobed, maple-like leaves. The three can be distinguished by leaf shape and fruit clusters: London planetree usually has two fruit balls on each stalk, and leaf lobes that are about as wide as they are long. American sycamore usually has single fruit balls, and leaf lobes that are wider than long. Oriental planetree has 3-5 fruit balls that hang beadlike on the stalk, and leaf lobes that are deeply incised and much longer than wide.

Like its American parent, London plane is a massive tree that can get more than 100 ft (10.7 m) tall with wide-spreading branches that can span 80 ft (24.4 m) or more. Several cultivars of London plane have been selected: 'Bloodgood' is more drought tolerant and resistant to anthracnose; 'Columbia' and 'Liberty' are resistant to powdery mildew and anthracnose; 'Pyramidalis' has branches that are more upright.

Location
London planetree was first discovered growing in London in the 1700's and now can be found lining the streets in cities throughout the world. It is especially popular in Europe, Asia and North America. (In Australia and South Africa, they plant oriental planetree along the streets.) London planetree does not grow in the wild.

Culture
