Viburnums belong to the genus Viburnum, which has about 150 species of shrubs and trees. Some species have inflorescences very similar to those of hydrangeas.The foliage is evergreen, semi-evergreen or deciduous depending on the species. They have opposite leaves or are arranged in whorls by 3. They are often strongly ribbed, sometimes lustrous, whole, toothed or lobed. The leaves of the deciduous viburnum take warm shades in the autumn. The flowers appear grouped - in panicles, cymes, bunches or corymbs - and almost always bear 5 lobes. They can be white, cream, or pink. Afterward appear very visible red fruits that are not edible for humans, but that birds appreciate. Viburnum flowering is usually spring-like, but there are exceptions such as the Viburnum tinus that blooms in winter.
