This genus includes the rowans (mountain ash) and whitebeams, and this present group consists of the rowans, technically known as the Aucuparia section. These are small, graceful trees or shrubs with attractive foliage, which in the rowans is usually pinnate, toothed or lobed and provides good autumn colour. In spring or early summer they produce dense corymbs of frothy white or pinkish flowers, which are followed by fruit varying in colour depending on the species. Many species are apomictic, i.e. self-fertile, and so seedlings are clones of the parent. For this reason there are many species, groups of which can be similar to one another.
Sorbus sambucifolia is called the Siberian mountain ash, although its wild distribution ranges from the Aleutian Islands to Siberia and down to Japan. It has only five or six pairs of leaflets on each leaf, clusters of rather few but relatively large white flowers, and quite large, globular, red fruit.
