distribution_en:

description_en: Genus of 8 species of annuals and perennials from mountainous regions of Australia, Tasmania, and New Zealand. They are grown mainly for their dense, hemispherical flowerheads of tiny, cup-shaped flowers, surrounded by leafy bracts and borne on stiff, unbranched stems. They are also cultivated for their basal rosettes of elliptic, obovate, spoon-shaped, or linear, hairy, mid-green to silvery white leaves. Grow perennial species in a rock garden or scree bed. In damp, frost-prone areas, most are best in an alpine house; grow C. globosa in an annual border. The flowerheads are useful for dried flower arrangements.
