Viburnum opulus, the guelder-rose or guelder rose (/ˈɡɛldər/) is a species of flowering plant in the family Adoxaceae (formerly Caprifoliaceae) native to Europe, northern Africa and central Asia.

Description

Flowers (left) and fruit

Viburnum opulus is a deciduous shrub growing to 4–5 m (13–16 ft) tall. The leaves are opposite, three-lobed, 5–10 cm (2–4 in) long and broad, with a rounded base and coarsely serrated margins; they are superficially similar to the leaves of some maples, most easily distinguished by their somewhat wrinkled surface with impressed leaf venation. The leaf buds are green, with valvate bud scales.

The hermaphrodite flowers are white, produced in corymbs 4–11 cm (2–4 in) in diameter at the top of the stems; each corymb comprises a ring of outer sterile flowers 1.5–2 cm in diameter with conspicuous petals, surrounding a center of small (5 mm), fertile flowers; the flowers are produced in early summer, and pollinated by insects. The fruit is a globose bright red drupe 7–10 mm diameter, containing a single seed. The seeds are dispersed by birds.

Names

The common name 'guelder rose' relates to the Dutch province of Gelderland, where a popular cultivar, the snowball tree, supposedly originated. Other common names include water elder, cramp bark, snowball tree, common snowball, and European cranberrybush, though this plant is not closely related to the cranberry. Some botanists also include the North American species Viburnum trilobum as V. opulus var. americanum Ait., or as V. opulus subsp. trilobum (Marshall) Clausen.

Phylogeny

Viburnum opulus is a member of the Viburnum genus which contains 160 to 170 species. It is classified in the subsection Opulus, which usually contains five species. Phylogenetic analyses suggest the following relationship between those species:
