'''''Sorbus aucuparia''''' ('''Rowan''', '''European Rowan''', '''Mountain ash''', or '''European mountain ash'''), is a species of the genus [[Sorbus]], native to most of [[Europe]] except for the far south, and northern [[Asia]]. In the south of its range in the [[Mediterranean region]] it is confined to high altitudes in mountains.<ref name=rushforth>Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins ISBN 0-00-220013-9.</ref><ref name=dvf>Den Virtuella Floran: [http://linnaeus.nrm.se/flora/di/rosa/sorbu/sorbaucv.jpg ''Sorbus aucuparia'' map]</ref>
Sometimes called "[[Mountain Ash]]",<ref name=vedel>Vedel, H., & Lange, J. (1960). Trees and Bushes in Wood and Hedgerow. Methuen & Co Ltd.</ref><ref name=arkive>Arkive: [http://www.arkive.org/species/ARK/plants_and_algae/Sorbus_aucuparia/more_info.html Rowan (''Sorbus aucuparia'')]</ref> ''Sorbus'' is unrelated to the true [[Fraxinus|Ash tree]] though the leaves are superficially similar.
It is a small to medium-sized [[deciduous]] [[tree]] typically growing to 8–10 m tall, more rarely 20 m, and exceptionally to 28 m.<ref>Tree Register of the British Isles</ref> The [[bark]] is smooth, silvery grey of young trees, becoming scaly pale grey-brown and occasionally fissured on old trees. The shoots are green and variably hairy at first, becoming grey-brown and hairless; the buds are conspicuous, purple-brown, and often densely hairy. The [[leaf|leaves]] are [[pinnate]], 10–22 cm long and 6-12 cm broad, with 9–19 (most often 13–15) leaflets; each leaflet is 3–7 cm long and 15–23 mm broad, with a coarsely serrated margin; they are variably hairy, particularly the petiole and leaf veins on the underside. The [[plant sexuality|hermaphrodite]] [[flower]]s are produced in large terminal [[corymb]]s 8–15 cm diameter with up to 250 flowers, the individual flowers 1 cm diameter, with five creamy-white [[petal]]s, and are insect pollinated. The [[fruit]] is a small [[pome]] 6–9 mm (rarely up to 14 mm) diameter, green at first, ripening bright red in late summer, and containing up to eight (most commonly two) small [[seed]]s. It is [[diploid]], with a [[chromosome]] count of 2''n''=34.<ref name=rushforth/><ref name=tfl>Trees for Life Species Profile: [http://www.treesforlife.org.uk/tfl.rowan.html Rowan]</ref><ref name=fnwe>Flora of NW Europe: [http://ip30.eti.uva.nl/BIS/flora.php?selected=beschrijving&menuentry=soorten&id=2736 ''Sorbus aucuparia'']</ref>
Widely grown as an ornamental tree in northern Europe, more locally in northern North America, where also sometimes naturalised.
==Cultivation==
==Cultivation==
Rowan is very tolerant of cold and is often found at high altitude on mountains; in the [[United Kingdom|UK]] it occurs at up to 1 000 m altitude, higher than any other tree, and in [[France]] up to 2 000 m.<ref name=arkive/><ref name=tfl/><ref name=afm2>Mitchell, A. F. (1982). ''The Trees of Britain and Northern Europe''. Collins ISBN 0-00-219037-0</ref>
It is very tolerant of a wide range of soil conditions, including thin acid soils and cracks in cliffs. It also fairly frequently grows as an [[epiphyte]] in clefts or cavities of larger trees such as [[Scots Pine]]s, though epiphytic specimens rarely have growing conditions adequate for them to reach maturity.<ref name=tfl/>
