A magnificent Black Walnut (Juglans nigra) stands as a spectacular beacon at the junction of the snaking path from the new Brookside Gate with the original peripheral path enclosing the 1846 Garden.
The earliest survey of the tree collection was made in 1915 by the Curator, Richard Irwin Lynch. He noted that the Black Walnut was one of the best trees in the Garden and one of the finest Black Walnuts in the British Isles. This is still true today, with the Garden’s specimen close to 25 metres tall. It is rare, even in its native territory of eastern and central United States, for specimens to attain this stature, since most are felled for their highly-prized timber. The deeply, furrowed, dark bark, almost latticed, the large pinnate leaves that turn a warm butter yellow in autumn and a vast, spreading crown, are amongst its outstanding features. In winter sunshine, the statuesque yet sinuous tracery of the bare-branched canopy casts an intricate shadow pattern on nearby Brookside Lawn.
