Japanese snowball (Viburnum plicatum)
Description
Viburnum plicatum (Japanese: yabudemari, oodemari), common name Japanese snowball, is a species of flowering plant in the family Adoxaceae (formerly Caprifoliaceae), native to mainland China, Korea, Japan, and Taiwan.Growing to 3 m (10 ft) tall, it is a deciduous shrub. The leaves are opposite, 5-10 cm (2-4 in) long and 3-6 cm broad, simple ovate to oval, with a serrated margin. The flowers are produced in flat corymbs 5-10 cm (2-4 in) in diameter, comprising a central cluster of fertile yellowish-white flowers 5 mm diameter, surrounded by a ring of showy, sterile flowers 2-3 cm diameter, which act as a target guide to pollinating insects. The fruit is an ovoid blue-black drupe 8-10 mm long. Plants from Taiwan are sometimes distinguished as Viburnum plicatum var. formosanum Liu & Ou. Viburnum plicatum is a popular ornamental plant, both in its native area and elsewhere in temperate regions. Some of the more popular cultivars are selected for having all of their flowers large and sterile with few or no fertile flowers; their flowerheads resemble a snowball, giving them the popular name "Japanese snowball bush". Cultivars of this type include 'Grandiflorum' and 'Rotundifolium'. Cultivars with wild-type flowerhead structure are sometimes described as a separate botanical form V. plicatum f. tomentosum. They include 'Cascade', 'Lanarth' and 'Rowallane'. Two cultivars in this group, 'Mariesii' and 'Pink Beauty', have gained the Royal Horticultural Society's Award of Garden Merit.
