Feathery gray-blue foliage covers the ground, growing flat as a pancake. Branches will root as they creep along the ground. The foliage takes on a light purple hue in winter. It can be staked for more height, forming a hump with a low, spreading skirt all around it. Grows best in sun and well drained soil. Garden size is 6" tall and 4' wide. Hardy to Zone 3.
