Although Black Walnut is not strictly native to the UK, the tree has been grown here for over 400 years and so Black Walnut can be considered as naturalised. Black Walnut tends only to be planted in Southern Britain where the spring and autumn frosts are less severe, although the species is fairly tolerant to exposure.
Black Walnut grows best on deep, medium to rich and moist soils as it will grow poorly on other types. Walnut trees are often grown on base-rich soils, although fertility and moisture is necessary for good timber production of high value, so often nitrogen-fixing nurse crops are used.
The leaves are brighter than the common walnut, although the nuts less edible.
