- Hardy to USDA Zone (3)4 Native to the Sakhalin Island of Russia, also found in 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).
