Rowan

The rowans or mountain-ashes are shrubs or trees in the genus Sorbus of the rose family, Rosaceae. They are native throughout the cool temperate regions of the Northern Hemisphere, with the highest species diversity in the Himalaya, southern Tibet and parts of western China, where numerous apomictic microspecies occur. The name rowan was originally applied to the species Sorbus aucuparia and is also used for other species in Sorbus subgenus Sorbus.Formerly, when a wider variety of fruits were commonly eaten in Europe and North America, Sorbus was a domestically used fruit throughout these regions. It is still used in some countries, but S. domestica, for example, has largely vanished from Britain, where it was traditionally appreciated. Natural hybrids, often including S. aucuparia and the whitebeam, Sorbus aria, give rise to many endemic variants in the UK.
