Common Name: Walnut
The walnut family like deep, well drained soil and full sun or part shade. Speculation on walnuts 'poisoning' the soil for other trees is true with the Black Walnut (J. nigra) which produces 'Juglone', a plant inhibiting substance. It also has other colouring properties used in the cosmetics (hair dye) and good industries.
