Betula populifolia is an important successional tree on burned, cleared, or abandoned land in the Northeast. It is closely related to Betula pendula Roth of Europe, B. neoalaskana of the Northwest, and several Asian taxa. This species is easily distinguished from the paper birch, with which it is often sympatric, by the long tapering apices of its leaves, its nonpeeling bark, and the characteristic expanded, black triangular patches on the trunks below the branches.
The Iroquois used Betula populifolia medicinally to treat bleeding piles, and the Micmac, to treat infected cuts and as an emetic (D. E. Moerman 1986).
The blue birches (Betula ×caerulea Blanchard) have been variously considered to repres species or a hybrid between B. papyrifera Marshall and B. populifolia Marshall (T. C. Brayshaw 1966) or B. papyrifera and the big blue birch B. caerulea-grandis (M. L. Fernald 1922). Both B. ×caerulea and B. caerulea-grandis have been shown in more recent experimental studies to be of hybrid origin between B. cordifolia Regel and B. populifolia (A. G. Guerriero et al. 1970; W. F. Grant and B. K. Thompson 1975; P. E. DeHond and C. S. Campbell 1989). Individuals of these hybrids combine characteristics of the parents, the infructescence scales and leaves somewhat resembling those of B. populifolia, and the habit and exfoliating reddish bark that of B. cordifolia.
