Betula populifolia 'Whitespire' Betula populifolia 'Whitespire'

Medium-size tree with a regular, pyramidal crown without heavy side branches. First year twigs dark brown, older bark white, not peeling. The triangular leaf has a conspicuously long, tapered tip. It is fresh green and turns golden yellow in autumn. For a long time it was assumed that ‘Whitespire’ originated from seed collected in Asia. It was later found that a filing error had been made and that ‘Whitespire’ is a seedling of B. populifolia. Tolerates air pollution, which means it can also be used in industrial areas.
