原生地・分布（英語）:

説明（英語）: Genus of about 20 species of evergreen, often spiny shrubs and small trees from dry, open woodland in tropical and subtropical Africa and Asia. The leaves are opposite, entire, and leathery. The tubular flowers, with 5 spreading petal lobes, are borne singly or in terminal or axillary cymes, and are followed by red or black, fleshy fruits. Although the flesh of these is edible and used for jam-making, the seeds are poisonous. In frost-prone regions, grow in a cool greenhouse or conservatory. In frost-free areas, grow outdoors in a shrub border, or as hedging.

耐寒性（英語）: Mostly frost tender; C. macrocarpa and its cultivars may survive short spells around 0°C (32°F).

繁殖（英語）: Sow seed at 15-18°C (59-64°F) as soon as ripe or in spring. Root semi-ripe cuttings in summer.
