"Although closely related to poison ivy, this attractive small tree from the eastern North American deciduous forests is not at all poisonous to the touch and is a pleasant addition to the garden throughout the year. Large pinnately-compound leaves with marginal teeth and a glossy upper surface are attractively dark-green in summer..." (Straley 1992).
