Crassula corallina is a small succulent plant with branching stems that can grow up to 8 cm long and root at the nodes. The leaves are fleshy, warty, and range in color from green, gray-green, to gray-brown, with a white waxy coating on the surface. The cross-section of the leaves is rhomboid, about 0.5 cm wide. The flowers are urn-shaped, white or cream-colored, and bloom continuously from spring to mid-summer.
The scientific name corallina comes from the Latin word "corallium," meaning "coral," referring to the coral-like appearance of its leaves.
Care Instructions for Crassula corallina
1. Light
Crassula corallina thrives in full sunlight and does not prefer partial shade. However, during the hottest summer afternoons, strong sunlight can scorch the leaves, so it is best to expose the plant to sunlight only in the morning and evening.
2. Soil
It can adapt to a wide range of soil pH levels but prefers porous, well-draining soil.
3. Cold Tolerance
Crassula corallina can tolerate temperatures as low as -1.1°C to 10°C.
4. Watering
Crassula corallina enjoys water and responds well to the "soak-and-dry" method. This involves soaking the soil from the bottom and letting it dry before watering again. During winter, water sparingly.
5. Fertilization
Apply granular or organic fertilizer once a year in early spring.
6. Repotting
Repot during the beginning of the active growing season, preferably in spring, as needed.
7. Propagation
Crassula corallina is typically propagated through cuttings, inheriting the robust propagation ability of the Sedum genus.
Additional Notes
Newly grown leaves of Crassula corallina are predominantly white, and close observation reveals a fine, white dotted pattern.
The plant blooms with small yellow flowers between April and June.
Native to the desert border areas of South Africa, it favors full sunlight, dry conditions, and good ventilation.
It tolerates partial shade but avoids hot and humid environments, as high summer temperatures can induce dormancy.
In winter, it can survive temperatures as low as -2°C if kept dry.
Compared to other Sedum plants, Crassula corallina prefers prolonged sunlight to maintain its short and compact form.
Optimal growth occurs between 18°C and 25°C. If the temperature drops below 5°C, it is best to manage the plant with no watering.
