Graptopetalum superbum, formerly known as Graptopetalum pentandrum subsp. superbum, is a stunning shrubby succulent with suberect to semi-decumbent stems and blush to lavender, heavily glaucous leaves that cluster in a rosette at the end of the stems. It can grow up to 8 inches (20 cm) tall, branching from the base. The rosettes are dense, nearly flat, and can reach up to 5 inches (12.5 cm) in diameter. The leaves are thick, fleshy, soon deciduous, oblong-obovate, with a deltoid mucro, and can grow up to 2.4 inches (6 cm) long and 1 inch (2.5 cm) wide. Old plants can have stems up to 7 feet (2.1 m) long, but this plant usually remains relatively compact, especially when grown in full sun.
The flowers are star-shaped, with 5 or 6 greenish-yellow petals with red tips, 2 or 3 crossbands, and scattered dots of the same color below. They appear on erect or ascending, multiple-branched inflorescences from late winter to early spring, and the inflorescences can reach up to 16 inches (40 cm) in length.
