原生地・分布（英語）:

説明（英語）: Genus of about 500 species of annuals, herbaceous or evergreen perennials, and evergreen shrubs and subshrubs, widely distributed in Europe, Asia, Africa, and particularly in Australasia and South Africa, where they usually occur in dry, sunny sites. They have woolly or hairy stems and alternate leaves, sometimes opposite or in basal rosettes, which are aromatic in some species. The flower-heads are daisy-like or shaving-brush-like, either borne singly or in corymbs, and "everlasting" when dried. Grow small, prostrate, or cushion-forming helichrysums in a rock garden, scree bed, or alpine house; taller perennials and subshrubs are suitable for a mixed or herbaceous border. In frost-prone climates, tender species, such as H. petiolare, are excellent in hanging baskets or containers; in warmer areas, use as annuals in borders or beds.

耐寒性（英語）: Fully hardy to frost tender.

栽培（英語）:

繁殖（英語）: Sow seed at 13-16°C (55-61°F), or in containers in a cold frame, in spring; sow seed of alpines in containers in an open frame as soon as ripe or in spring. Divide perennials in spring. Root heel or semi-ripe cuttings of shrubby species in summer and over-winter in frost-free conditions.

病害虫（英語）: Powdery mildew may be a problem.
