説明（英語）: Genus of about 7 species of low-growing, spreading or upright, evergreen shrubs and subshrubs, found in scrub, thickets, and woodland margins, and on mountains, from S.W. Europe to S. Greece, Turkey, and Algeria. They are cultivated for their 5-lobed, funnel-shaped, blue or white flowers, produced in leafy, terminal cymes, mainly in summer. Leaves are linear, lance-shaped, elliptic, or obovate, and hairy. The hardiest species are ideal for an open position in a rock garden or raised bed.
