- Deciduous tree, to 40 ft (12 m) tall and 30 ft (9 m) wide, fast growing, vase-shaped. Bark dark brown, slightly fissured and finally broken into thin plates. Leaves opposite, pinnately compound (odd), 7-11 leaflets, ovate to ovate-oblong, 6-12 cm long, tip acuminate, base rounded or wedge-shaped, dull green above, hairless (glabrous) or nearly so below; leaves yellow in fall. Flowers yellow-green, in glabrous clusters (panicles), 6-8 cm long. Fruit about 1 cm across, blue-black.
- Sun and partial shade
- Hardy to USDA Zone (3)4 Native to Sakhalin (a narrow island, one of the territories disputed between Japan and Russia), Korea, northern Japan and western China. Often sold as Phellodendron amurense, however, it is more vase-shaped and its bark is less corky [but this may not be the case (Dirr, 1998)] and brown (not gray as is that of P. amurense). It is difficult to separate these two species (Dirr, 1998).
