distribution_en:

description_en: Genus of about 100 species of annuals, perennials, and evergreen shrubs and subshrubs from coastal plains to forest or laurel-covered clifftops in the Mediterranean and Atlantic islands. They are grown mainly for their simple, often softly hairy or white-woolly leaves, arranged in opposite pairs. Tubular to bell-shaped, 2-lipped flowers are borne in whorled spikes in summer. They need long, hot summers to thrive. In warm, dry climates, grow at the front of a mixed or shrub border, in a rock garden, or in a small courtyard garden. Where winters are cold and damp, grow as foliage plants in a cool greenhouse.

hardiness_en: Half hardy to frost tender.

propagation_en: Sow seed of tender species at 13-16°C (55-61°F) in spring; sow seed of hardier species in containers in a cold frame in spring. Divide perennials in early spring. Root soft-wood cuttings of shrubs in late spring, with bottom heat; take semi-ripe cuttings in late summer.

pests_en: Trouble free.
