Rowan 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 mountains of western China and the Himalaya, 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
Sorbus anglica cliffs, quarries and rocky hillsides. It appears to be indifferent to soil pH. Occasional specimens are known from oak woodland. Research suggests Sorbus anglica developed from a cross between Sorbus porrigentiformis and Sorbus aucuparia. Sorbus anglica Sorbus anglica, the English whitebeam, is a species of whitebeam tree in the family Rosaceae. It is uncommonly found in Ireland and the United Kingdom, with an entire British population estimated at about 600 individuals. Sorbus anglica grows as a small tree or shrub, often with multiple stems. The leaves are broader than most other Sorbus, with lobes whose bases are incised up to
