Infra familial classification:

distribution_en:

description_en: Genus of about 100 species of annuals, biennials, and predominantly evergreen, mat- or cushion-forming perennials. They have small rosettes of hairy leaves and produce stemless or short-stemmed, tubular-based flowers, with flat or cup-shaped lobes, singly or in umbels from late spring to late summer. Most occur in the mountains of the N. hemisphere, growing in rock crevices, scree, or turf. The high-alpine (Aretian), cushion-forming species are superb for a well-ventilated alpine house; most of the remainder are ideal for a rock garden, scree bed, or trough.

hardiness_en: Fully hardy, but the Aretian species need protection from excessive wet, especially in winter.

cultivation_en:

propagation_en: Sow seed in containers in an open frame as soon as ripe or in autumn. Root single rosettes as cuttings in early to midsummer. Keep moist, but water from below to avoid wetting the rosettes.

pests_en: Prone to aphids under glass, and to fungal diseases in damp conditions. Remove dead rosettes to reduce the risk of infection.
