Sorbus takhtajanii is represented in several British arboreta and is reasonably distinct on account of its dark green leaves with a bright white underside. The leaves are strongly toothed in their upper half. It is one of the Armenian species whose introduction is described above. All of them have proved to be relatively slow-growing, having champions of no more than 4–5 m (TROBI) as yet.
