Aeonium arboreum var atropurpureum 'Schwarzkopf', or Black Tree Aeonium, is a very interesting Aeonium. The 8-inch (20 cm) rosette of almost black leaves on an up to 3-foot (1 m) high light gray trunk is very showy. They are easy to culture and are hardy in USDA zone 10.
Blooming Time: In summer. The bright yellow flowers set against the almost black foliage are very showy.
Culture: Aeonium arboreum var atropupureum 'Schwarzkopf' need full sun to light shade with a well drained potting mix. In the greenhouse, we use a soil mix consisting of 2 parts sand to 1 part peat moss to 1 part loam with small gravel added to increase drainage. Plants are allowed to thoroughly dry in-between waterings. We fertilize Aeonium once during the growing season with a balanced fertilizer. During the winter months, the temperature is dropped to 50° F (10°C) and we restrict water to about once a month, or just enough to keep the foliage from shriveling.
Propagation: Aeonium arboreum var atropurpureum 'Schwarzkopf' is easily propagated by cuttings in the spring.
Aeonium arboreum var atropurpureum 'Schwarzkopf' was featured as Plant of the Week June 20-26, 2003.
