Additional Information

A generally better choice than the species type, Betula platyphylla var. japonica is a larger, graceful tree with thinner, spreading branches and striking pure white bark. It is especially well adapted to wet soilsand does not do well in dry situations. Less subject to the borer troubles of B. papyrifera in the Midwest, although still susceptible.
