European walnut/ Common Walnut
bot. Juglans
Thanks to its dark, noble appearance, the wood of the European walnut is a highly valued and widely used wood in furniture and interior design. The wood is often striped or grained and, especially in combination with the lighter sapwood, offers an extremely decorative and appealing look. As a rule, the walnut trees are dug out together with the rootstock, from which the sought-after burl veneers are extracted. Supply of the valuable wood on the timber market is rather low, which enhances its exclusive character. Due to the limited availability of the European walnut, the American walnut (juglans nigra) is used as an option.

Natural yellowing.
Origin
- Introduced from Eastern Europe and the Near East into Central and Western Europe (as a fruit tree). The most magnificent examples are found in France, the most beautiful nut trees in Switzerland can be found at Lake Lucerne.
