Burkwood viburnum (Viburnum burkwoodii)

Description

Viburnum × burkwoodii (Burkwood viburnum) is a hybrid flowering plant in the family Adoxaceae (formerly Caprifoliaceae). It is a cross of garden origin between V. carlesii and V. utile, grown for its early, strongly scented flowers. Growing to 2.5 m (8 ft) tall and broad, V. × burkwoodii is a deciduous shrub with glossy, dark green oval leaves on well-branching, stiff stems. The sweetly scented flowers are pinkish white, borne in spring, and followed later in the season by red fruits ripening to black. Viburnum is a genus of about 150-175 species of shrubs or (in a few species) small trees in the moschatel family, Adoxaceae. Its current classification is based on molecular phylogeny.It was previously included in the family Caprifoliaceae.The member species are native throughout the temperate Northern Hemisphere, with a few species extending into tropical montane regions in South America, Ukraine, Russia, and southeast Asia. In Africa, the genus is confined to the Atlas Mountains. In Ukraine, Viburnum opulus (kalyna) is seen as a national symbol, an emblem for both the Koliada festivities and the concept of young girl-s love and tenderness. It is the key element of the Ukrainian traditional wreath.The generic name originated in Latin, where it referred to V. lantana.The leaves are opposite, simple, and entire, toothed or lobed; cool temperate species are deciduous, while most of the warm temperate species are evergreen. Some species are densely hairy on the shoots and leaves, with star-shaped hairs.The flowers are produced in corymbs 5-15 cm across, each flower white to cream or pink, small, 3-5 mm across, with five petals, strongly fragrant in some species. The gynoecium has three connate carpels with the nectary on top of the gynoecium. Some species also have a fringe of large, showy sterile flowers round the perimeter of the corymb to act as a pollinator target.The fruit is a spherical, oval, or somewhat flattened drupe, red to purple, blue, or black, and containing a single seed; some are edible for humans, but many others are mildly poisonous. The leaves are eaten by the larvae of many Lepidoptera species.
