Cacti and succulents, Perennials
Takes full sun in cooler climates only. Among the best succulents for decorative effects, in pots or in the ground. Fleshy leaves are held in rosettes at branch tips. After several years, rosettes produce a single flower stalk in spring or summer; branches that have flowered die.
With age, plants become leggy; to encourage branching, cut back branches several inches below rosettes. Cuttings are easily rooted: let dry for a few days, then plant in sandy soil and keep barely moist until new growth appears.
Grows to 3 ft. tall and wide. Each branch tip carries a 6–8-in.-wide rosette of bright green, fleshy leaves. Yellow flowers in long clusters. ‘Atropurpureum’, with magenta-and-green rosettes, is more striking and more widely grown than the species. Hybrid ‘Zwartkop’, sometimes called black rose, has very dark purple (nearly black) rosettes up to 10 in. across; it can reach 5 ft. tall.
Showy plant with 12-in.-wide rosettes of green leaves variegated in light yellow or creamy white and edged with red. Usually grows 1 1/2–2 ft. high and wide but can mound up to 4 ft. high. Flowers are cream-colored. Does not respond well to pruning. ‘Starburst’ is similar, but with less yellow in the leaves.
