This series of short articles about trees in the Belfast Botanic Gardens is compiled by members of the Friends group and Gardens staff. We aim to build up to a comprehensive archive of trees in Belfast Botanic Gardens. Each article illustrates a tree growing in Belfast Botanic Gardens together with information from a range of sources. Where possible we will give the tree tag number - these are the small aluminium discs, usually fixed on the tree trunk, 2 to 3m above ground level.

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.
