Korean Viburnum (Viburnum Carlesii)
The origin of the generic name is not clear. The genus comprises some 120 species distributed throughout the temperate regions of the northern hemisphere; only occasionally are they found in the tropical zone, in Java. The species is named after W. R. Charles, one-time consul in China and an avid plant collector. Native to Korea, it was first introduced into Britain in 1900. It is a deciduous shrub about 1.5m (5ft) high. Theare whitish-pink, very fragrant, and borne in dense cymes, and the leaves are opposite and toothed. The fruit is a one-seeded drupe.
Viburnum is propagated by means of seeds which are stored for the winter at a temperature of about 8° C (47° F) stratified in spring and sown in the autumn. It may also be budded or the scion with a leaf can be grafted on to Viburnum lantana rootstock. Propagation by summer cuttings with a heel is also a possible but not very successful method. Viburnum requires good, deep loamy, on the moist side, with humus, and prefers a sunny situation. The Korean viburnum is attractive as a solitary specimen in small gardens and parks. Its salient features are its early flowering and strong fragrance.
