原生地・分布（英語）:

説明（英語）: Genus of about 10 species of mat-forming, often rhizomatous perennials and subshrubs, previously included in the genera Chrysanthemum or Leucanthemum, from exposed rocky areas in N. Africa, with one species from Spain. They are cultivated for their solitary, large, daisy-like flowerheads, surrounded by prominent, usually green bracts, borne on erect, branched or unbranched stems, mainly in spring and summer. The deeply or shallowly 3-lobed leaves are hairy and sometimes silvery. Grow in a sunny rock garden, a raised bed, at the base of a warm, sunny wall, or in an alpine house.

耐寒性（英語）: Most are hardy to -10°C (14°F) in very well-drained soil, but resent excessive winter wet.

繁殖（英語）: Sow seed in containers in a cold frame in spring. Root soft-wood cuttings in early summer.
