Sorbus aucuparia, Linn. (Pyrus Aucuparia, Gaertn.). European Mountain-ash. Rowan Tree. Fig. 3649. Round-headed tree, 20-40, occasionally 60 ft. high: young branchlets pubescent, grayish brown when older: petioles more or less tomentose; lfts. 9-15, oblong to oblong-lanceolate, serrate, entire toward the base, dull green above, pubescent beneath or rarely glabrous, 3/4 - 2 in. long: fls. white, 1/3 in. across, in flat, 4-6-in.-broad, tomentose or sometimes almost glabrous corymbs; stamens about as long as petals: fr. globose, about 1/3 in. across, bright red. May, June. Eu. to W. Asia and Siberia. H.W. 3:54, pp. 78, 79. Var. dulcis, Kraetzl (var. moravica, Zengerling). Almost glabrous: petioles purplish; lfts. oblong-lanceolate, 2-3 in. long, glaucescent beneath, usually serrate only above the middle. The frs. are of an agreeable acid flavor and recommended for preserves. The tree thrives well in cold northern climates where hardly any other fr.-tree will grow. G.M. 52:887. Var. rossica, Spaeth, is similar and also bears edible fr., but the lfts. are larger and broader and more serrate. Var. Beissneri, Rehd. (var. dulcis laciniata, Beissn., not var. laciniata, Hartm.), is a handsome and graceful form of var. dulcis with the lfts. pinnately lobed and the lf .-stalks and young branchlets bright red. G.W. 3:267. Var. fastigiata, Loud., forms a narrow pyramidal tree, with upright branches. Var. pendula, Hort., has long and slender pendulous branches. M.D. 1911, p. 246. Var. integerrima, Lange. Lfts. entire or nearly so. Var. Fifeana, Dipp. (var. fructuluteo, Hort.). Fr. yellow.

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.[1][2]

Sometimes called "Mountain Ash",[3][4] Sorbus is unrelated to the true 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.[5] 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 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 hermaphrodite flowers are produced in large terminal corymbs 8–15 cm diameter with up to 250 flowers, the individual flowers 1 cm diameter, with five creamy-white petals, 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 seeds. It is diploid, with a chromosome count of 2n=34.[1][6][7]

Widely grown as an ornamental tree in northern Europe, more locally in northern North America, where also sometimes naturalised.

Cultivation

Rowan is very tolerant of cold and is often found at high altitude on mountains; in the UK it occurs at up to 1 000 m altitude, higher than any other tree, and in France up to 2 000 m.[4][6][8]

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 Pines, though epiphytic specimens rarely have growing conditions adequate for them to reach maturity.[6]

  • Sorbus aucuparia subsp. glabrata (syn. S. glabrata). Subarctic regions, from Iceland, northernmost Scotland (Orkney, Shetland), northern Scandinavia, northwest Russia, and also locally at tree line in central Europe in the Alps and Carpathians. Shrubby; leaves and shoots less hairy.
  • Sorbus aucuparia subsp. praemorsa. High altitudes in the Mediterranean region in France (Corsica) and Italy (Sicily and Calabria).
