原生地・分布（英語）:

説明（英語）: Genus of about 60 species of evergreen shrubs and small trees found on sandy heath, on dry, rocky and sandy coasts, and in scrub in Australia. They are grown for their foliage and their very colourful flowerheads, both of which are suitable for dried flower arrangements. Leaves are alternate, sometimes whorled, linear to ovate, leathery, usually very boldly toothed, and often pinnatifid. Spherical to ovoid, often thistle-like flowerheads, borne at the ends of the shoots, consist of many slender, usually yellow florets enclosed by overlapping, sometimes coloured bracts. In frost-prone areas, grow in a cool greenhouse; elsewhere, grow in a border, against a warm wall, or in a sunny courtyard.

耐寒性（英語）: Frost tender; D. formosa survives short periods near 0°C (32°F).

栽培（英語）:

繁殖（英語）: Sow seed at not less than 18°C (64°F) in spring, ideally singly, in small containers. Root soft-wood cuttings with bottom heat in summer; rooting may be slow.

病害虫（英語）: In warm areas, Phytophthora root rot may be fatal. In soil containing too much phosphate, plants may become chlorotic.
