Viburnum Viburnums are deciduous or evergreen shrubs or small trees, although Ohio's native viburnums are not evergreens.
Winter buds are naked, valvate, or imbricate.
Leaves are opposite with toothed, entire, or lobed margins. Flowers are small in umbel or panicle-like clusters. Fruits are drupes. Petioles have narrow, not wavy, margins. Branches are rather rigid.
