Crassula sarcocaulis or Bonsai Crassula

Crassula sarcocaulis, or Bonsai Crassula, is a succulent sub-shrub native to South Africa. With the aspect of a small tree and an ability to look older than it really is, these plants are often used as subjects for bonsai culturing. Plants will reach to 10-12 inches (25-30 cm) tall with a spread of about 18 inches (35 cm) wide, depending on how they are trained. Branching appears nearly dichotomous. Leaves are light green and awl-shaped to 1/2 inch (1.2 cm) long. The plants are easy to culture and are hardy in the landscape in USDA zones 8-11.

Blooming: In summer, the plant is covered with white to pink flowers. Individual flowers are 0.24 inches (7 mm) long. When in flower, it is one of the showiest Crassulas that I have ever seen.

Culture: Crassula sarcocaulis needs full sun to partial shade, requiring a well-drained soil mix. In the greenhouse, we use a soil mix consisting of 1 part peat moss to 1 part loam to 2 parts coarse sand. Plants are well watered and allowed to dry before watering again. We fertilize the plants only once during the growing season with a balanced fertilizer diluted to 1/2 the strength recommended on the label. This is done in the spring if you want a great floral show in the summer. During the winter months, temperatures in the greenhouse are never allowed to drop below 50°F (10°C). Water is restricted during this period and only given enough to keep the leaves from shriveling.

Propagation: Crassula sarcocaulis is readily propagated by cuttings.

Crassula sarcocaulis was featured as Plant of the Week December 1-7, 2006.
