The Birch Tree (Betula sp.) is named for its shiny white bark, since the ancient origin of the Indo-Germanic word means "light? or "shiny?.
The birch is a symbol of spring.
For Northern Europeans, it is the most important mythical tree.

Birch wood was first used for manufacturing furniture during the Biedermeier period.
The light wood has different uses: among other things, for furniture, turnery, parquet floors and children's toys.
