Stonecrop, Creeping –
Seldom seen, this Stonecrop species is native to the Southeastern USA. It forms a low carpet of thick, succulent silvery-grey leaves that become burnished with bronze during the summer. Small clusters of starry white flowers appear in early summer. Excellent for hot, sunny locations. Perfect for the rock garden, wall, alpine containers or edging a pathway. Easily divided in spring. Plants remain evergreen in mild winter regions. Prune back to 2 inches in spring, if desired. Possibly hardy to Zone 4 or colder. Introduced by international breeder Syngenta Flowers.

Select a site with full sun to light shade and very well-drained soil.
Plant in spring, spacing plants 6 inches to 2 feet apart, depending on the variety. Prepare the garden bed by using a garden fork or tiller to loosen the soil to a depth of 12 to 15 inches, then mix in a 2- to 4-inch layer of compost. Dig a hole twice the diameter of the pot the plant is in. Carefully remove the plant from its container and place it in the hole so the top of the root ball is level with the soil surface. Carefully fill in around the root ball and firm the soil gently. Water thoroughly.
Apply a thin layer of compost each spring, followed by a 2-inch layer of mulch to retain moisture and control weeds. Water plants during the summer if rainfall is less than 1 inch per week. After the first killing frost, cut stems back to an inch or two above soil line. Divide plants every 3 to 4 years as new growth begins in the spring, lifting plants and dividing them into clumps.
