Cultural Significance

Hazel holds profound significance in Celtic and European folklore. Hazel wands were believed to have magical properties and were used for divination and dowsing. In Celtic tradition, the hazel tree represented wisdom and inspiration, with hazelnuts falling into the Well of Wisdom. The wood was used to make protective talismans, and hazel branches feature in fairy tales like "Cinderella" as wish-granting trees.
