Graptopetalum filiferum (S.Watson) Whitehead
Graptopetalum filiferum is a unique mat-forming succulent that forms short-stemmed rosettes of metallic green leaves with hyaline margins and a characteristic long hear-like reddish-brown tip. The rosettes have 75 to 100 leaves. They are almost flat to the ground and up to 4 inches (10 cm) in diameter. Leaves are fleshy, glabrous, spatulate, up to 1.2 inches (3 cm) long and up to 0.5 inches (1.2 cm) wide.
The flowers are star-shaped, usually 5- to 6-merous, white, apically with bright dark brownish-red blotches, and appear in late spring and early summer.
Graptopetalum filiferum is native to Mexico (Chihuahua). It grows on rocks at elevations around 7,050 feet (2,150 m).
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 Graptopetalums 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 the plants regularly over summer, letting 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 easily propagated 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 and falls off. By then, the new little plant had rooted and sprouted new leaves.
