Low growing stonecrops are ideal plants for growing on stone walls. Plant them on top of the walls and in niches between the stones. Here are some great kinds for such places. Most of these are perennials.
Gold moss stonecrop
This plant is also known as wall-pepper since it often grows on walls and among rocks. Native to Europe, this low growing perennial forms a mat. Typically, it is less than four inches in height. The fleshy leaves are triangular with blunt tips. During the early summer, the vivid yellow blooms open in clusters. These are star-shaped. Its other common name, gold moss, refers to the yellow blooms as well as the tiny, moss-like foliage.
