Senecio cylindricus - Asteraceae

Senecio cylindricus is a perennial succulent sub-shrub native to South Africa. The bluish grey cylindrical leaves reach about 4.5 inches (11.4 cm) long by 5/16 of an inch (10 mm) thick. In nature, the plant will reach from 12-24 inches (30-60 cm) tall with an equal spread. They are very easy plants to grow and they are hardy in the landscape in USDA zones 10-12.

Blooming: In the greenhouse, our plants have never bloomed.

Culture: Senecio cylindricus need a well-drained soil mix with full sun to light shade. In the greenhouse, we use a soil mix consisting of 3 parts coarse sand to 1 part loam to 1 part peat moss, with small gravel added to ensure good drainage. The potting mix needs to be slightly acidic. The plants are well watered and allowed to dry thoroughly before watering again. We fertilize these plants only once during the growing season with a balanced fertilizer diluted to ˝ the strength recommended on the label. During the winter months, the plants are allowed to dry and are only watered enough to keep the leaves from shriveling. The nighttime temperatures are never allowed to fall below 50°F (10°C).

Propagation: Senecio cylindricus is propagated from stem cuttings.

Senecio cylindricus was featured as Plant of the Week September 14-20, 2007.
