Betula pendula 'Alba' is the classic Silver Birch, admired for its brilliant white peeling bark, light airy canopy, and elegant drooping branches that bring year-round structure and softness to the garden.
Silver Birch 'Alba' grows to 15-20 metres tall and 5-6 metres wide with a slender upright form. Fine green leaves turn golden-yellow in autumn before dropping to reveal the striking white bark. It looks especially effective planted in loose clusters, as an avenue, or as a seasonal contrast against darker evergreen foliage.
Silver Birch tolerates urban conditions and a range of soils, performing best in cool to temperate regions including VIC, Tasmania, the ACT, the NSW Southern Highlands, and elevated parts of WA and SA. It prefers full sun to part shade with moist, well-drained soil.
