Similar to Yellow Birch, which has pubescent (rather than glabrous) pistillate scales that are 6-13 mm long. Like Yellow Birch, the twigs of Sweet Birch have a wintergreen odor when broken but have a sweeter taste. Sometimes called Cherry Birch because the dark, smooth bark of young trees resembles some species of Cherry.
