The Common Hazel (Corylus avellana) is one of Europe’s most valuable wild trees — and not just because it gives us the delicious hazelnuts we love to eat. Every part of this plant — from its leaves and bark to its catkins and nuts — carries centuries of traditional use for health, nutrition, and home remedies.

Often found at the edge of forests or in hedgerows, hazel has been both a source of food and natural medicine, symbolizing vitality, fertility, and protection since ancient times. Let’s explore the remarkable benefits of this humble tree that many people overlook.
🌿 How the Hazel Tree Grows
Hazel is technically a large shrub rather than a tall tree, usually reaching 3–6 meters in height. It forms multiple stems growing from a single root, creating a dense, bushy appearance.
- In winter, the tree rests but already carries the closed male flowers (catkins).
- In early spring, the catkins open and release yellow pollen, while small, red-tipped female flowers appear on the branches — these later develop into hazelnuts.
- In summer, the green leaves and fruits mature.
- By autumn, the nuts ripen and fall, providing food for both people and wildlife.
This seasonal rhythm has made the hazel tree a symbol of renewal and abundance for centuries.
