distribution_en:

description_en: Genus of about 50 species of perennials from open mountain screes and grassland in South America. The fleshy, sometimes rhizome-like tubers spread to form clumps, 30-60cm (12-24in) across. They produce erect stems with alternate or scattered, linear to lance-shaped, mid- to grey-green leaves, usually 7-12cm (3-5in) long, with twisted leaf-stalks. Showy, funnel-shaped, 6-tepalled flowers, 3.5-10cm (1 1/2-4in) long (smaller in the dwarf species), are borne in summer; they are produced in loose, often compound, few- to many-rayed, terminal umbels, 7-12cm (3-5in) across. They are ideal for a mixed or herbaceous border, although A. pygmaea and A. hookeri are best grown in an alpine house. Many species are good for cut flowers. Contact with foliage may aggravate skin allergies.

hardiness_en: Hardy to -10°C (14°F), although A. aurea and A. ligtu and their hybrids will tolerate brief falls in temperature to -15°C (5°F).

cultivation_en:

propagation_en: Sow seed in containers in a cold frame as soon as ripe. Plant out seedlings by the potful to avoid damaging the tubers. Divide established clumps in autumn or very early spring.

pests_en: Susceptible to slug damage and viruses; red spider mites may be a problem under glass.
