About this tree

Betula pendula, commonly known as silver birch, is native to Europe and parts of Asia. It is a medium-sized, elegant deciduous tree that typically grows up to 25 m tall. Its most distinctive feature is its bright white bark, which peels in thin layers and often develops black fissures with age. The tree has slender, drooping branches and delicate, triangular leaves that turn golden yellow in autumn. In early spring, male and female catkins appear before leaf-out, providing pollen for insects, particularly bees. Silver birch is a keystone species in many ecosystems, supporting over 300 insect species, including numerous moths and butterflies. Birds such as siskins and redpolls feed on its seeds, while woodpeckers and owls have shown a preference for older silver birch trunks for their nests. It tolerates both poor soils and cold climates, often acting as a pioneer species on disturbed land. Interestingly, silver birch bark contains betulin, a compound with antifungal and antibacterial properties, historically used in traditional medicine. Its airy canopy allows light to reach the forest floor, promoting undergrowth diversity. In gardens and parks, the silver birch is valued for its graceful form and ecological benefits. Used by humans since the Mesolithic era, silver birches remain among the more culturally significant trees. Even today, traditional craftspeople make canoes, baskets, containers, and clothing from its bark, and sugar from birch water (xylitol) has become a common alternative sweetener. In addition, birch trees have also had their place in the art of the Pre-Raphaelites and Gustav Klimt, and in the poetry of writers such as Robert Frost.
