distribution_en: E.Asia, Polynesia

description_en: Genus of about 7 species of deciduous trees and shrubs from woodland in E. Asia and Polynesia. They have alternate, entire or lobed, toothed leaves. Male and female flowers are borne on separate plants. B. papyrifera, the only widely cultivated species, is grown for its large leaves, pendent male catkins, and unusual fruit. It needs hot summers to ripen its wood and achieve tree stature, and then may be an attractive isolated specimen. Its tolerance of pollution, heat, and poor soil has made it a popular tree for urban locations. In areas with cool summers, it grows as a large shrub and is suitable for a shrub border.

hardiness_en: Fully hardy to frost tender.
