The rosemary is an evergreen perennial shrub, only representative of its kind in the Labiatae family. It originates from the entire Mediterranean basin, in particular in the coastal areas. In the wild it grows in barren and sunny soils. It becomes part of the Mediterranean scrub, colonizing cliffs and gorges among the rocks. It is widespread from sea level up to 650 meters above sea level. In the islands, especially in Sardinia and in Corsica, it is possible to find it up to 1500 meters above sea level. Flowering occurs during the spring (with blue-purple flowers); it is a very rustic plant and fears prolonged frost.
