Sedum : cultivated stonecrops
"Although neglected by general gardening books, sedums - often called stonecrops - are popular with gardeners who realize that plants do not have to be ostentatious, expensive, or difficult to grow to be charming. Sedums are sun-loving, drought-resistant, mostly hardy, and provide masses of color. They are prized by alpine and rock gardeners as much as by succulent enthusiasts."
