Phedimus spurius

Phedimus spurius, the Caucasian stonecrop or two-row stonecrop, is a species of flowering plant in the family Crassulaceae. It is a low-growing, spreading succulent with stems that creep along the ground and root as they grow. P. spurius occurs naturally in the rocky subalpine meadows of Georgia, northern Iran, and northeastern Turkey. It has naturalized in Europe, often found along roadsides, walls, and waste areas, escaping cultivation to form persistent colonies. It is widely grown for its tolerance of drought and rocky conditions. Wild populations and cultivars vary in color from white to red; greener-leaved plants produce paler blooms and those with red or purple foliage developing deeper-colored flowers....read more on Wikipedia.
