'''''Platanus × acerifolia''''', the '''London plane''', '''London planetree''', or '''hybrid plane''', is a tree in the genus ''[[Platanus]]''. It is usually thought to be a [[Hybrid (biology)|hybrid]] of ''[[Platanus orientalis]]'' (oriental plane) and the ''[[Platanus occidentalis]]'' (American sycamore). Some authorities think that it may be a [[cultivar]] of ''P. orientalis''.

The London Plane is a large [[deciduous]] [[tree]] growing to 20–35 m (exceptionally over 40 m) tall, with a trunk up to 3 m or more in circumference. The [[bark]] is usually pale grey-green, smooth and exfoliating, or buff-brown and not exfoliating. The [[leaf|leaves]] are thick and stiff-textured, broad, palmately lobed, superficially [[maple]]-like, the leaf blade 10–20 cm long and 12–25 cm broad, with a [[Petiole (botany)|petiole]] 3–10 cm long. The young leaves in spring are coated with minute, fine, stiff hairs at first, but these wear off and by late summer the leaves are hairless or nearly so. The [[flower]]s are borne in one to three (most often two) dense spherical [[inflorescence]]s on a pendulous stem, with male and female flowers on separate stems. The [[fruit]] matures in about 6 months, to 2–3 cm diameter, and comprises a dense spherical cluster of [[achene]]s with numerous stiff hairs which aid wind dispersal; the cluster breaks up slowly over the winter to release the numerous 2–3 mm seeds.

*'''Augustine Henry'''. This is a tall growing variety, with very large, pale green leaves. It produces a strong leader and a cylindrical trunk.<ref name = Bean/>
*'''Bloodgood''', This is one of the first cultivars to be selected for anthracnose resistance. It is a rounded tree with deep green leaves that turn a poor yellow in fall. The plant tolerates poor cultural conditions, including heat, drought and poor soil. Recent observations indicate susceptibility to ozone.
*'''Columbia'''. Resists mildew and anthracnose, this tree has deeply-lobed, dark green leaves.<ref name = Rushforth>Rushforth, K. (1999). ''Trees of Britain and Europe''. [[Harper Collins]] ISBN 0-00-220013-9.</ref>
*'''Liberty'''. A U.S. National Arboretum introduction, this pyramidal tree grows vigorously. It shows good tolerance for mildew, anthracnose, heat and drought.<ref name = Rushforth/>
*'''Metzam''' (Metroshade), A new introduction that grows strongly with a pyramidal habit, this cultivar is also said to be disease resistant with lustrous green foliage that emerges with a reddish cast.<ref name = Rushforth/>
*'''Mirkovec'''. Has a dwarf, shrubby habit and unusual variegated lobed leaves with pink, cream and bronze regions.<ref name = Rushforth/>
*'''Pyramidalis'''. A cultivar or cultivar group common in London, with rich glossy green leaves, and a characteristic tendency to produce straight branches, compared to sinuous branches ones in other forms.<ref name = Bean/>
*'''Suttneri'''. Leaves are variegated creamy white.
*'''Yarwood'''. Very resistant to powdery mildew and highly susceptible to anthracnose. Poor structure. Being abandoned in California.<ref>Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan.</ref>
