Aeonium sp. is just one of the 38 species of Aeoniums native to the Canary Islands and Mediterranean Region. I received this plant as a cutting a few years ago. In 3 years, it has grown to be 18 inches (45 cm) tall by 12-16 inches (30-40 cm) wide. The dark green rosettes are up to 6 inches (15 cm) across. It is a freely-branching species with a smooth brown bark and a nice, round-headed form. Individual leaves are 3 inches (7.7 cm) long by 1.25 inches (3.2 cm) wide, with small teeth along the margins. The margins in summer have a red tinge to them when grown in full sun. It displays a very interesting growth habit and makes a great container plant.
Blooming: Most Aeoniums bloom in the winter months here in the greenhouse, but this one hasn't bloomed in the 3 years it has been growing here.
Culture: Aeonium sp. needs full sun to partial shade, with a well-drained soil mix. In the greenhiouse, we use a soil mix consisting of 1 part peat moss to 1 part loam to 2 parts coarse sand or perlite. The plants are winter-growing succulents. In late summer, the watering of these plants is stepped up. Plants are well watered and allowed to dry before watering again. We fertilize them only once during the growing season with a balanced fertilizer. During the winter growing season, nighttime temperatures are never allowed to drop below 55°F (13°C). In early spring, water is restricted to harden the plants off for the hot summer months. During the summer months, the plants should be watered only enough to keep the leaves from shriveling.
Propagation: Aeonium sp. is propagated by cuttings and from seed if available.
Aeonium sp. was featured as Plant of the Week November 10-16, 2006.
