Viburnum is a genus of deciduous or evergreen shrubs in the family Adoxaceae, comprising 150-175 species. It is native to the temperate Northern Hemispheres, with a few species extending into tropical montane regions in South America and Southeast Asia. It is confined to the Atlas Mountains in Africa. Species of Viburnum in cool temperate regions are deciduous, while most of the warm temperate species are evergreen. The leaves are opposite, simple, and entire, toothed ot lobed. Some species have hairy leaves and shoots, with star-shaped hairs. The five-petalled flowers are produced in winter or spring, in white to cream or pink color. Some species have strongly fragrant flowers. These are followed by berry-like fruits which are spherical, oval or flattened drupe, red to purple, blue or black color, containing one seed. Some of the berries are edible for humans, though many others are mildly poisonous to people. Many species of Viburnum have become popular ornamental plants in garden and landscape, with their showy flowers and berries, fragrance, and good autumn color of some forms. Evergreen plants rarely needs pruning. Prune winter-flowering deciduous shrubs in spring, and summer-flowering shrubs in mid-summer, after the flowers have faded. Viburnum tinus is native to the Mediterranean region and Macatonesia. It is commonly known as Laurustinus, Laurustinus Viburnum or Laurestine. Laurus signifies the leaves' similarities to bay laurel; and tinus means 'tenth born'. It is a shrub, growing to 2-7m tall with evergreen leaves. Small white flowers are borne in clusters in late winter to spring, and they are followed by black fruits. It is a popular evergreen shrub widely cultivated for its winter flowering habit in regions with mild winter. Viburnum opulus (Guelder Rose, Water Elder, European Cranberrybush, Cramp Bark, Snowball Tree) is native to Europe and Asia. It is a deciduous shrub growing to 4-5 m tall, with maple-like leaves, and bearing white flowers in late spring, followed by red berries and red autumn foliage. It is commonly grown as ornamental plant for its flowers and berries. Viburnum opulus grows best in moist, moderately alkaline soils, though tolerating most soil types.
