Crooked Yellow Stonecrop

Petrosedum rupestre (PEH-tro-SEE-dum rue-PES-tree)

Family: Crassulaceae Non-native Groundcover (<1 ft)

'Angelina' stonecrop is a cultivar mainly grown for its striking spiky yellow leaves that turn an attractive red-orange color with cold weather in the fall. In the wild, this plant is often found along walls, shingle and warm grassy places on sandy soils. It avoids acid soils. Plant in the full sun, although it tolerates light shade, and in a site that provides good drainage. Gardeners often use the plant as a groundcover in a rock garden, draping over a rock wall, or hanging basket. It is a mat-forming plant that spreads rapidly. It looks best in small groups or mass planted as a border front or lining a walkway or patio. This plant is resistant to damage by deer and rabbits and tolerates drought, air pollution, and dry rocky soils. The leaves tend to fall off easily; however, the fallen leaves can be used to propagate new plants. Stems and leaves may be eaten raw when very young and tender. As the stems and leaves age, but before the plants flower, the edible parts may still be eaten if they are briefly cooked. The sap can irritate the skin of some people and the leaves, eaten in quantity, can cause stomach upsets. A good ground cover plant for a sunny position. The plant is used on 'green roof' and 'green wall' systems in Korea where plants are incorporated into the structure of the building to provide habitats for wildlife and insulate the building, helping to improve the environment. Insects, Diseases, and Other Plant Problems: No serious diseases or insect problems, except for occasional slugs and snails. Avoid wet or poorly drained conditions. VIDEO Created by Laura Barth for "Houseplants, Succulents, and Cacti," a plant identification course developed in partnership with Longwood Gardens. Note that 'Angelina' stonecrop is referred to by the synonym, Sedum rupestre 'Angelina'.
