Sorbus aucuparia, commonly called rowan (, also UK: ) and mountain-ash, is a species of deciduous tree or shrub in the rose family. The tree has a slender trunk with smooth bark, a loose and roundish crown, and its leaves are pinnate in pairs of leaflets on a central vein with a terminal leaflet. It flowers from May to June in dense corymbs of small creamy-white flowers and develops small red pomes as fruit that ripen from August to October and are eaten by many bird species.
