description_en: Genus of 40 species of rosette-forming, stiffly hairy annuals and evergreen biennials, perennials (some monocarpic), and shrubs, from stony hillsides, cliffs, open woodland, and grassy steppes in Europe, the Canary Islands, the Mediterranean, Africa, and W. Asia. They are grown for their often one-sided, cyme-like panicles or spikes of roughly funnel-shaped, sometimes bell-shaped, blue, purple, yellow, white, or red flowers, usually 1-2cm (1/2-3/4in) long, borne mainly in summer. The bristly-hairy, usually stalkless leaves are borne in basal rosettes and on the flower stems. Grow echiums in an annual, mixed, or herbaceous border. In frost-prone climates, grow tender species in a cool greenhouse. All parts may cause mild stomach upset if ingested; contact with the foliage may irritate skin.

hardiness_en: Fully hardy to frost tender.

cultivation_en:

propagation_en: Sow seed of perennial and biennial species at 13-16°C (55-61°F) in summer, overwintering seedlings at 5-7°C (41-45°F). Sow seed of annuals in spring, either in situ or under glass. Root semi-ripe cuttings of shrubby perennials in midsummer.

pests_en: Outdoors, slugs may attack young growth. Under glass, whiteflies and red spider mites may be a problem.
