原生地・分布（英語）: W. & S. N.America

説明（英語）: Genus of approximately 150 species of annuals, perennials, and evergreen shrubs and subshrubs, occurring mostly in desert and mountains in W. USA. They are cultivated for their beautiful, often white-woolly foliage and their dense heads, umbels, or cymes of small, long-lasting flowers, cupped in involucres of toothed or lobed bracts. They range from compact, cushion-forming plants with linear to ovate or rounded leaves in basal rosettes, to large shrubs with opposite, alternate, or whorled leaves. Grow the smaller, rosette-forming species in a rock garden or alpine house, the larger ones in a shrub border. In frost-prone areas, grow tender species in a cool greenhouse or conservatory.

耐寒性（英語）: Fully hardy to frost tender.

栽培（英語）:

繁殖（英語）: Sow seed of hardy species in containers in an open frame in autumn. Sow seed of tender species in spring at 13-16°C (55-61°F). Root individual rosettes of cushion-forming species as cuttings in spring or early summer. Water only from below. Root semi-ripe cuttings of shrubs in summer.

病害虫（英語）: Prone to aphids and red spider mites under glass.
