Betula populifolia 'Whitespire'
'Whitespire' is best known for its upright form, non-exfoliating white bark, dark green leaves and attractive yellow fall color. Vegetatively propagated plants of this cultivar are considered to have better resistance to bronze birch borer. 'Whitespire' was originally named as a cultivar of Betula platyphylla var. japonica when introduced into commerce in 1983, but that designation was subsequently changed when it was determined 'Whitespire' was in fact a gray birch.
