Gray birch

Gray birch is a narrow, pyramidal tree of cool climates. Bright green leaves turn a yellow fall color. Older trees develop a chalky white bark that does not peel. A good selection for poor soils and other difficult sites, it also demonstrates some resistance to bronze birch borer (BBB).

This plant has some cultivated varieties. Go to list of cultivars.

Cultivars and their differences 

Whitespire  (Betula populifolia ‘Whitespire’):  Good resistance to bronze birch borer.  The name 'Whitespire' was incorrectly assigned to Betula platyphylla.  It is now assigned to Betula populifolia and the plants are often sold under the name 'Whitespire Senior' to avoid confusion.
