description_en: Genus of about 60 species of biennials and short-lived perennials found in temperate regions of Europe and Asia, usually in rocky sites and on dry, grassy wasteland. They are cultivated for their tall, slender inflorescences of large, stalkless or short-stalked, funnel-shaped, 5-petalled, brightly coloured flowers, often double in cultivars, which are borne in summer. Suitable for a mixed border, or for growing along a wall; they are attractive to butterflies and bees.
