×Graptoveria 'Amethorum' is a strangely attractive succulent that forms compact stemless rosettes of greyish-green leaves tipped with green margins. The leaves are thick and keeled, with a faint line running down the center. When grown in bright sunlight, the edges of the leaves can blush pink to red. Rosettes grow up to 3 inches (7.5 cm) in diameter. Flowers are pink and appear on long arching stems.
USDA hardiness zone 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (+10 °C).
How to Grow and Care
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 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.
The Graptopetalums are generally easy to propagate by seeds, leaf cuttings, or offsets. Any rosette that breaks off has the potential to root and start a new plant. Even a leaf that drops off will root below the parent plant and produce a new rosette quickly. The new plant feeds off the leaf until it shrivels up and falls off. By then, the new little ghost plant had rooted and sprouted new leaves.
