Thyme is any member of the genus Thymus of aromatic perennial evergreen herbs in the mint family Lamiaceae. Thymes are relatives of the oregano genus Origanum. They have culinary, medicinal, and ornamental uses, the species most commonly cultivated and used for culinary purposes being Thymus vulgaris.
In some Levantine countries, and Assyria, the condiment za'atar (Arabic for both thyme and marjoram) contains many of the essential oils found in thyme. It is a common component of the bouquet garni, and of herbes de Provence.
Thyme is sold both fresh and dried. While summer-seasonal, fresh greenhouse thyme is often available year-round. The fresh form is more flavourful, but also less convenient; storage life is rarely more than a week. However, the fresh form can last many months if carefully frozen.
