CALCAREUM

Syn. S. tectorum L. var. calcareum (Jordan) Cariot & St. Lager. A species recorded in 1849 by Jordan, but is regarded by many authorities as a variety of S. tectorum, the first recorded case of this was in the year 1854, hence the above synonym. In regard to botanical status we have accepted the authority of Flora Europaea Vol. 1 (1964). S. calcareum is a native of the French Alps growing on calcareus rocks. It has large grey-green rosettes 6 cm in diameter or more across with glabrous leaves conspicuously tipped with purple on the both sides of the leaves. Flowers are pale pink, but seldom produced. It is an easy species to grow and a very good garden plant.
