Sorbus commixta (Japanese Rowan) is a species of rowan native to Japan, the far east of Russia on Sakhalin, and in Korea on the island of Ulleungdo.[1][2][3]

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.[2][3][4]

Plants from Hokkaidō, the Kuril Islands and Sakhalin are sometimes distinguished as Sorbus commixta var. sachalinensis, with larger leaflets up to 9 cm long.[3]

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).[3]
