Distribution en:

Description en: Genus of about 20 species of often rhizomatous, summer-flowering, herbaceous perennials and deciduous and evergreen subshrubs from open habitats, often in mountainous areas of the Mediterranean and S.W. Asia. They have spreading to upright stems bearing simple, aromatic leaves in opposite pairs, and inflorescences in spiked whorls, which are sometimes panicle- or corymb-like. The elongated, tubular or funnel-shaped, 2-lipped flowers are borne amid conspicuous, often brightly coloured bracts, which remain attractive for many weeks. Some origanums, O. dictamnus, O. majorana, O. onites, and O. vulgare and their cultivars, are used as culinary herbs. Grow smaller species in a rock garden, scree bed, alpine house, or at the front of a border; grow larger ones in a herbaceous border or herb garden. All attract bees and other insects.
