Japanese Wingnut Akin to the Causasian wingnut, this Japanese native was brought into cultivation in Europe in the late 1800s, though it is still relatively rare in cultivation. Boasts gorgeous yellow Autumn colour, and fantastic long racemes of winged seed in Autumn into winter. Growing into a large broad tree, it makes a beautiful specimen for a medium to large garden.
