Description
Crassula corallina subsp. macrorrhiza is a small succulent with a tuberous main root and short, erect, or longer decumbent or prostrate branches. The tuber can reach up to 0.5 inches (1.3 cm) in diameter. The leaves are gray-green to gray-brown with a white waxy coating, usually with a rounded tip, and can grow up to 0.2 inches (0.5 cm) long.

How to Grow and Care for Crassula corallina subsp. macrorrhiza
Light: Crassula plants prefer full sun to partial shade. However, intense afternoon sun in the hottest period of summer can burn the leaves of the plants. Most Crassulas can be grown indoors if given enough light.
Soil: They are not particular about soil pH, but Crassulas require very porous soil with excellent drainage.
Hardiness: Crassula corallina subsp. macrorrhiza can withstand temperatures as low as 30 to 50 °F (-1.1 to 10 °C), USDA hardiness zones 10a to 11b.
Watering: These plants have typical watering needs for succulents. Avoid overwatering using the "soak and dry" method, where the soil is soaked with water, slowly drained, and left to dry out before watering again. Reduce watering in winter.
Fertilizing: Crassulas will benefit from a small amount of organic fertilizer in mid-spring when they start actively growing.
Repotting: Repot as needed, preferably in spring, at the beginning of active growth.
Propagation: Crassulas are generally started by leaves or stem cuttings. They can also be grown from seeds and offsets.
