Cultivated since ancient times, it was introduced to Europe by the Greeks and Romans, who valued its nutritious fruit and precious wood. In ancient Rome, walnuts were considered luxury foods, reserved for feasts and religious ceremonies. Over the centuries, the **Common walnut** spread throughout Europe, where it became a symbol of wisdom and fertility. Today, it is appreciated throughout the world for its wood, its nuts and its symbolic aura, combining legends and traditions.

The **Common walnut** has leaves rich in **nutrients**, which, as they fall, enrich the soil with organic matter. This decomposition of the leaves promotes more fertile soil and improves soil structure, which in turn benefits other surrounding plants and trees. Walnut wood is also sought after for its hardness, beauty and durability. It is prized for cabinet-making, top-of-the-range furniture and decorative objects. By introducing walnut into the forest, our foresters **are diversifying the species** and **are developing a resource** of high economic quality. ### Common Walnut - Overview ### Common Walnut - Overview The **Common walnut** can reach heights of 15 to 25 metres, and even up to 30 metres in ideal conditions. It has a broad, rounded crown with spreading branches, giving it an imposing appearance. Its silhouette is often recognisable from afar because of its large, spreading branches. The trunk is straight and massive, with light grey bark that becomes rougher and cracked with age. Older specimens may have deeply furrowed bark, adding to their **robust appearance**. The leaves of **Common walnut** are deciduous and alternate. They are made up of 5 to 9 oval leaflets, often in an odd number, with a larger terminal leaflet. The leaflets have smooth margins and a shiny dark green appearance above, lighter below. The **Common walnut** is a **monoecious tree**, which means that it bears separate male and female flowers on the same tree. The male flowers appear in long (10 to 15 cm long), greenish catkins in spring, before the leaves appear. The female flowers, which are smaller and more discreet, are found at the tips of young shoots, often in twos or threes. They are also greenish and sometimes go unnoticed.

Ideal growing temperatures are between 12 and 20°C, but it can tolerate winter temperatures down to around -25°C once mature. Its water requirements are relatively high, especially when young trees are being established and during periods of active growth. Irrigation is often necessary in the event of prolonged drought. However, it does not tolerate excess water, hence the importance of well-drained soil. **Common walnut** is susceptible to a number of diseases, including **bacteriosis** (black spots) and**anthracnose**, which affect leaves and fruit. Good spacing between trees to ensure good air circulation and avoid excess humidity helps to reduce the risks. ### Common walnut's Wood The wood of **Common walnut** is widely used in **cabinetmaking** to make top-of-the-range furniture. Its fine grain, patterns and dark brown colour with varying shades make it an ideal choice for elegant, durable furniture. Walnut veneer is particularly popular for covering surfaces or furniture because of its **refined aesthetic**. The wood is sliced into thin sheets to cover other woods, allowing its luxurious appearance to be enjoyed with less material. Although its cost and rarity make it a rare choice for large structures, wood from **Common walnut** is used for certain **frameworks** or **beams** in buildings where aesthetics and durability are preferred. Its mechanical properties make it a robust and durable wood. ### Common walnut's symbolism The ancient Greeks saw the **Common walnut** as a tree sacred to **Athena**, goddess of wisdom, reinforcing its association with knowledge and intelligence. The **Common walnut** also has a **mystical and occult dimension** in certain cultures, often linked to its large roots that plunge deep into the ground. It is sometimes associated with divination rituals and magical practices. In Europe, witches were believed to gather around walnut trees, and the tree often featured in legends surrounding occult practices. Perfect for **Halloween**, isn't it? ### Our selection of trees Our goal is to enable anyone to do something that benefits nature and helps us to live in a more harmonious world.
