In site of its common name, it is not related to begonias but to grapes. In its native southeast Asia and Indonesia it climbs trees and shrubs by forked tendrils or cascades down rocks. The flowers are not ornamental and rarely seen. It needs very warm temperatures and high humidity for best growth. Lower light levels during winter in northern climates will cause older leaves to shed, requiring pruning.
