description_en: Genus of over 250 species of long-lived, evergreen shrubs and small trees, 1-20m (3-70ft) tall. They are found in acid soil in woodland areas from N. India and the Himalayas to China and Japan, and south to N. Indonesia, Java, and Sumatra. The usually glossy, mid- to dark green leaves are simple, alternate, and lance-shaped to elliptic, with toothed margins. Popular for their bold foliage and abundance of showy, white, pink, red, or yellow flowers, camellias have been extensively hybridized to produce a range of flower types (see panel, right). The flowers may be solitary, paired, or clustered, and are sometimes fragrant. In the following descriptions, flower sizes of cultivars have been defined as follows: miniature, to 6cm (2 1/2in); small, 6-8cm (2 1/2-3in); medium, 8-10cm (3-4in); large, 10-13cm (4-5in); very large, 13cm (5in) or more across. Camellias are elegant shrubs for a border or a woodland garden; they also make excellent specimen plants, both outdoors in open ground or in containers. In frost-prone areas, grow half-hardy and tender species in a cool greenhouse. The flowers are suitable for cutting and exhibition.

hardiness_en: Fully hardy to frost tender.

propagation_en: Root leaf bud or semi-ripe cuttings of the current year’s growth from late summer to late winter, or graft in late winter.

pests_en: Susceptible to aphids, scale insects, and vine weevils. A harmless sooty mould may grow on the honeydew produced by aphids and scale insects on the leaves. Virus diseases and leafy gall may blemish flowers and leaves. Leaf spot and honey fungus may also be a problem.
