The American walnut tree is prevalent in Florida, Texas, Nebraska, Canada and Kansas as well as in some parts of Europe. For centuries, walnut has been one of the most popular types of wood. The tree can grow as high as 40 meters and have adiameter of up to three meters. Its wood is almost knotless. Walnut heartwood has a dark-brown to violet-black colouring while the sap wood is rather grey-brown to light yellow in colour. Over time, the heartwood can darken to some degree. Variations in colour and grain as well as the distinctly visible growth rings give the wood a particularly ornamental appearance. American walnut, which is one of the most beautiful and refined types of wood, is used predomi nantly in timber construction and parquet flooring. When used for flooring, the wood is steamed to intensify the colours
