Sorbus commixta, the Japanese rowan (七竈 nanakamado, ナナカマド), is a species of flowering plant in the family Rosaceae, native to Japan, Sakhalin (in the Russian Far East), and the Korean island of Ulleungdo.[2][3][4]
Name
The specific epithet commixta means "mixed or mingled together".[5]
Its Japanese name, nana-kamado, literally means "seven (times in the) stove" and alludes to its sturdiness as firewood, as it does not get entirely consumed by the fire of a stove even after repeated use.[6]
Description
It is a small to medium-sized deciduous tree growing to 7–10 m (23–33 ft) tall, rarely 18 m (59 ft), with a rounded crown and brownish to silvery-grey bark. The leaves are 20–30 cm (8–12 in) long, and pinnate. The leaves consisit of 11-17 leaflets, each 4–7 cm (2–3 in) 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 in diameter, with five white petals and 20 yellowish-white stamens; they are produced in corymbs 9–15 cm (4–6 in) in diameter in late spring to early summer. The fruit is a bright orange to red pome 7–8 mm in diameter, maturing in autumn.[3][4][7]
Plants from Hokkaidō, the Kuril Islands and Sakhalin are sometimes distinguished as Sorbus commixta var. sachalinensis, with larger leaflets up to 9 cm long.[4]
Cultivation and uses
Outside its native range, it is grown as an ornamental tree, 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).[4] 'Embley' has gained the Royal Horticultural Society's Award of Garden Merit.[8]

The wood is hard and the tree's name derives from the saying that even after putting it into a stove (kamado) seven (nana) times, it remains unbumed.
