Walnut is a deciduous broadleaf tree native to south east Europe and south west China. The trees are usually 40 to 60 feet (12 to 18 metres) in height and develop a crown of the same size. The lifespan of a walnut tree depends on its species but they can survive anywhere between 50 and 250 years. The trees were first introduced to Britain by the Romans principally for their nuts which have a high nutritional value.
Walnut wood is used in the manufacture of flooring, furniture, musical instruments, panels, veneers and gun-stocks.
