'''''Acer pseudoplatanus''''', '''Sycamore''' (or '''Sycamore Maple''', to distinguish it from other plants called [[sycamore]]) is a species of [[maple]] native to central [[Europe]] and southwestern [[Asia]], from [[France]] east to [[Ukraine]], and south in mountains to northern [[Spain]], northern [[Turkey]], and the [[Caucasus]].<ref name=fe>Flora Europaea: [http://rbg-web2.rbge.org.uk/cgi-bin/nph-readbtree.pl/feout?FAMILY_XREF=&GENUS_XREF=Acer&SPECIES_XREF=pseudoplatanus&TAXON_NAME_XREF=&RANK= ''Acer pseudoplatanus'']</ref><ref name=rushforth>Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins ISBN 0-00-220013-9.</ref> In [[Scotland]], the Sycamore is known as the Plane tree, although it is not a member of the ''[[Platanus]]'' [[genus]].
It is a large [[deciduous]] [[tree]] that reaches 20–35 m tall at maturity, with a broad, domed crown. On young trees, the [[bark]] is smooth and grey but becomes rougher with age and breaks up in scales, exposing the pale-brown-to-pinkish inner bark. The [[Leaf|leaves]] are opposite, 10–25 cm long and broad with a 5–15 cm petiole, palmately veined with five lobes with toothed edges, and dark green in colour; some [[cultivar]]s have purple-tinged or yellowish leaves. The leaves are often marked with black spots or patches which are caused by the fungus [[Rhytisma acerinum]]<ref>http://www.garden-centre.org/Sycamore.htm Sycamore profile</ref>.
The monoecious yellow-green [[flower]]s are produced in spring on 10–20 cm pendulous [[raceme]]s, with 20-50 flowers on each stalk. The 5–10 mm diameter [[seed]]s are paired in [[Samara (fruit)|samara]]s, each seed with a 20–40 mm long wing to catch the wind and rotate when they fall; this helps them to spread further from the parent tree. The seeds are mature in autumn about 6 months after pollination.<ref name=rushforth/><ref name=humphries>Humphries, C. J., Press, J. R., & Sutton, D. A. (1992). ''Trees of Britain and Europe''. Hamlyn Publishing Group Ltd. ISBN 0-600-57511-X.</ref>
The flowers produce abundant nectar, which makes a fragrant, delicately flavoured and pale-coloured honey.

==Cultivation==
==Cultivation==
It is noted for its tolerance of wind, [[urban area|urban]] [[pollution]] and [[sodium chloride|salt]] spray, which makes it a popular tree for planting in [[city|cities]], along [[road]]s treated with salt in winter, and in [[coast]]al localities. It is cultivated and widely [[naturalisation (biology)|naturalised]] north of its native range in northern Europe, notably in the [[British Isles]] and [[Scandinavia]] north to [[Tromsø]], [[Norway]] (can ripen seeds north to [[Vesterålen]]); [[Reykjavík]], [[Iceland]]; and [[Torshavn]] on the [[Faroe Islands]]. It now occurs throughout the [[British Isles]], having been introduced in the 17th century.<ref>Preston, Pearman & Dines. (2002). ''New Atlas of the British Flora''. Oxford University Press.</ref>

In [[North America]], escapes from cultivation are most common in [[New England]], [[New York City]] and the [[Pacific Northwest]]. It is planted in many temperate parts of the [[Southern Hemisphere]], most commonly in [[New Zealand]] and on the [[Falkland Islands]].

The popular cultivar 'Brilliantissimum' is notable for the bright salmon-pink colour of the young foliage.
