description_en: Genus of 150 or more species of ever-green, semi-evergreen, and deciduous shrubs, sometimes trees, from thickets and woodland, mainly in N. temperate regions, but extending to S.E. Asia and South America. They are cultivated for their foliage, flowers, and fruits. The mostly lance-shaped to rounded, entire or toothed, sometimes lobed leaves are arranged in opposite pairs, occasionally in whorls of 3; they are often rough and prominently veined, and, in most deciduous species, colour attractively in autumn. The sometimes fragrant, white or cream, pink-flushed, or wholly pink flowers are salverform to tubular, or tubular-trumpet-shaped, each with 5 usually spreading lobes. They are borne in terminal or axillary panicles, clusters, corymbs, or cymes, which are often spherical or domed. Some species have flowers in flattened heads, similar to those of "lacecap" hydrangeas, in which the small, fertile central flowers are surrounded by larger, flat or saucer-shaped, sterile ray-florets. The ornamental fruits are usually spherical or ovoid, and may be red, blue, or black. Viburnums are suitable for a shrub border or woodland garden. Grow V. macrocephalum against a wall. Many show self-incompatibility; fruiting is often best if several seedlings of the same species are planted together so that cross-pollination can occur. The fruits of viburnums may cause mild stomach upset if ingested.

hardiness_en: Fully hardy to frost hardy.

cultivation_en:

propagation_en: Sow seed in containers in a cold frame, or in a seed bed, in autumn. Take greenwood cuttings of deciduous viburnums, and semi-ripe cuttings of evergreens, in summer.

pests_en: Aphids and viburnum beetles may be a problem, particularly on V. lantana, V. opulus, and V. tinus. V. tinus is susceptible to whiteflies. All are prone to honey fungus and leaf spot.
