Tylecodon sulphureus (Toelken) Toelken
Cotyledon sulphurea, Tylecodon sulphureus var. sulphureus
This species is native to South Africa (Northern Cape).
Tylecodon sulphureus is a small, sparingly branched succulent with a tuberous base and short erect branches that bear thick fleshy green leaves. The tuber grows up to 1.2 inches (3 cm) in diameter. Leaves are slightly grooved on the upper surface, up to 1 inch (2.5 cm) long and up to 0.3 inches (0.8 cm) wide. The tubular flowers are greenish-yellow and up to 0.5 inches (1.3 cm) long. They appear on erect flat-topped thyrses in late summer after the plant loses its leaves.
The specific epithet "sulphureus" means "sulfur-colored" and refers to the color of the flowers.
How to Grow and Care for Tylecodon sulphureus
Soil: Well-draining soil mix is the key to healthy Tylecodon. Poor drainage and overwatering most commonly cause root rot in both indoor and outdoor plants.
Light: Tylecodons can survive direct sunlight exposure without any problems, but they will grow beautifully when in shadow.
Hardiness: Tylecodon sulphureus can withstand temperatures as low as 30 to 50 °F (-1.1 to 10 °C), USDA hardiness zones 10a to 11b.
Watering: As winter is the growing season, Tylecodons require careful watering during the winter until the spring. Get the soil wet, and then wait until it is dry before watering again. In the summer, reduce watering to once per month.
Fertilizing: Use liquid fertilizer for cacti and other succulents during the winter months.
Repotting: You do not need to repot these plants often. You can do it when you see that the container becomes too small or shallow.
Propagation: Tylecodons can be cultivated either by seed or by cuttings.
