Graptopetalum superbum (Kimnach) Acev.-Rosas
Graptopetalum pentandrum subsp. superbum
Graptopetalum superbum, formerly known as Graptopetalum pentandrum subsp. superbum, is a succulent with thick, fleshy, pale gray-lavender to pink leaves that cluster in rosettes at the end of thick stems. The rosettes are open, flat, and up to 5 inches (12.5 cm) in diameter. Old plants have been noted with stems up to 7 feet (2.1 m), but more typically, this plant remains fairly compact, especially when grown in full sun. In late winter to early spring arise up to 2 foot (60 cm) tall, multi-branched inflorescences, holding small, star-shaped flowers with greenish-yellow petals with red markings on the tips.
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
The rules for Graptopetalum care are similar to those for most succulents. All require lots of sunlight to look their best. They require gritty, porous soil with excellent drainage. Water regularly over the summer months and let the soil dry out between waterings. Minimal water is required over winter. Overwatering is a cause of root rots, and the plant can get several pest infestations. Fertilize once during the growing season with a balanced fertilizer diluted to 1/4 strength.
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 plant has rooted and sprouted new leaves.
