The common walnut, Juglans regia, is probably a native of SE Europe to China but was widely spread by the Romans. Although the Botanic Gardens is near the Northern limit in Europe, trees in Belfast will form nuts in a good year.
The common walnut is easily distinguished from the black walnut (Juglans nigra) as the common walnut has only 5 or 7 leaflets on each compound leaf whereas the black walnut has 10 to 20. In winter it may be distinguished from the ash by the grey/brown buds, clearly distinct from the black buds of the ash.
