|Sorbus commixta subsp. var.||Japanese rowan|
It is a small to medium-sized deciduous tree growing to 7–10 m (rarely to 18 m) tall with a rounded crown and brownish to silvery-grey bark. The leaves are 20–30 cm long, pinnate with between 11-17 leaflets 4–7 cm long and 1–2.5 cm broad, with an acuminate apex and serrated margins; they change to a deep purple or red in autumn. The flowers are 6–10 mm diameter, with five white petals and 20 yellowish-white stamens; they are produced in corymbs 9–15 cm diameter in late spring to early summer. The fruit is a bright orange to red pome 7–8 mm diameter, maturing in autumn.
Outside of its native range, it is grown as an ornamental tree in Europe and North America, hardy in zones 5-9. It grows best in moist, well-drained soil, in full sun. A number of cultivars have been selected, the most popular being 'Embley' (with fastigiate branching) and 'Serotina' (flowering later in early summer).
