    Some larger, diverse conventional nurseries in the Midwest and Eastern USA sell the Amur Cork Tree, even a few cultivars of it. Like Black Walnut, it is not beautiful when younger, but if a tree is all by itself and full-grown, it is good-looking, even awesome. This species has escaped cultivation in southeast Pennsylvania along forest edges, which does not make me happy. It is sort of stinky, especially when the leaves or fruit are crushed. It is not as tolerant of hard urban conditions as some literature has presented it. It is dioecious, so that there are separate male and female trees. Three cultivars of it are male as 'His Majesty, Macho, and Shademaster,' which are better to plant than any females, so they should not escape cultivation. I don't think the fruit is really good for American bird species. It is a tropical-looking tree of medium-coarse texture. Its opposite, compound leaves are 10 to 15 inches long, dark lustrous green, with 5 to 13 leaflets. and the stout twigs have horseshoe-shaped leaf scars; with a poor yellow-brown to fairly good yellow fall colour. It is native to northern China and to Japan. There are supposed to be about 10 species of Corktrees in Asia, but they are not very different.
