viburno

Viburno is the Italian common name for the plant genus Viburnum, a large group of shrubs and small trees in the family Adoxaceae. The genus comprises about 150 species, native primarily to the temperate regions of the Northern Hemisphere, with additional species in Southeast Asia and the Mediterranean. Viburnum species are widely cultivated for ornamental use and vary in size from compact groundcovers to small trees.

Most viburnums are deciduous, though several evergreen species exist in warmer regions. They typically have opposite, simple leaves with serrated margins. Many species produce conspicuous flower clusters in spring, arranged in flat-topped cymes or panicles and often white or pale pink. The flowering period is followed by drupes that range in color from red to blue-black, which attract birds and other wildlife.

Taxonomically, Viburnum was traditionally placed in Caprifoliaceae but has since been assigned to Adoxaceae based on genetic evidence. The genus is diverse, with many hybrids and cultivars developed for landscape use. Notable species include Viburnum opulus (Guelder-rose), Viburnum tinus (laurustinus, evergreen in mild climates), Viburnum plicatum (Japanese snowball), and the fragrant hybrids Viburnum × bodnantense and Viburnum × burkwoodii.

In horticulture, viburnums are valued for versatility, tolerance of a range of soils, and appeal across seasons—flowers in spring, foliage and fruit through the year, and in some cases ornamental berries in winter. They generally prefer well-drained soil and can tolerate partial shade, with pruning often performed after flowering. Some parts of the plant are toxic if ingested by humans, while birds commonly feed on the fruit.
