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 frutescens is an easy and attractive small rowan, although it does not seem to be widely known. It is a very small tree, so far with us not growing high, but branching and occasionally suckering, so that it makes a small thicket. It has lots of white fruit, first produced while the plants are still young.
