Thyme is widely cultivated for its strong flavor, which is due to its content of thymol.Thyme is best cultivated in a hot sunny location with well drained soil. It is generally planted in the spring and thereafter grows as a perennial. Thyme retains its flavor on drying better than many other herbs. Thyme is sold both fresh and dried. The fresh form is more flavorful but also less convenient; storage life is rarely more than a week. While summer-seasonal, fresh thyme is often available year-round. Fresh thyme is commonly sold in bunches of sprigs. A sprig is a single stem snipped from the plant.
