Cacti and succulents
Most aeoniums are native to the Canary Islands. Their fleshy leaves are held in rosettes at branch tips. After several years, the rosettes may produce a single large flower stalk in spring or summer; branches that have flowered die. These cool-season growers go dormant in summer to save water. During dormancy, they may appear sick and lose leaves—but when the weather cools and the plants get a little water, they perk up and regrow leaves.
Plant in well-drained soil; cut back on irrigation in summer. With age, most aeoniums grow leggy. To encourage branching, cut back branches several inches below rosettes anytime except during summer dormancy. Rosettes tend to be smaller after growing out from pruning. Cuttings are easily rooted: let dry for a few days, then plant in sandy soil kept barely moist until new growth appears.
