Thistle Sage (Salvia carduacea) is a native annual herb in the Lamiaceae (Mint) family that grows in southern and central California, primarily in hot, dry inland areas. It comes closest to the coast in northern Santa Barbara County. It tends to grow in sandy or gravelly places, at elevations from 0-4500 feet. It has a distinctive thistle appearance but is not related to true thistles. It is more closely related to Chia (S. columbariae). It is almost always grown from seed and is sometimes included in desert seed mixes.
