Graptopetalum amethystinum is a rare species that looks more like moon rocks than a plant. This succulent plant has plump, rounded leaves in lovely shades of lavender, pink, and green. The leaves have a powdery coating that adds to the eerie, moon rock look. If grown in a hanging planter, the plant will spill over the edges up to 18 inches (45 cm).
The rules for Graptopetalums care are similar to those for most succulents. Container-bound plants thrive in a mixture of peat, sand or other grit, topsoil and a little bit of compost. Full sun is the best situation but they will also grow in partial sun with slightly rangy results. Graptopetalums need excellent drainage and moderate water. You can tell when to water by sticking your finger in the soil. If it is dry several inches down or the fleshy leaves are looking shriveled, you should water. Overwatering is a cause of root rots and the plant can get several pest infestations. Summer growers. Graptopetalums require gritty porous soil with excellent drainage. Water regularly over the summer months letting the soil dry out between waterings. Minimal water is required over winter. Fertilize once during the growing season with a balanced fertilizer diluted to ¼ strength. All do best in sun or part sun excluding Graptopetalum bellum which prefers light shade.
