Crassula thunbergiana, commonly known as Thunberg’s Crassula, is a succulent plant native to the rocky outcrops and sandy plains of South Africa’s Eastern Cape and Western Cape provinces. It is a moderately growing species that typically reaches 0.5-2 feet (0.15-0.6 meters) in height and spreads 0.5-1.5 feet (0.2-0.5 meters) wide. The plant forms a dense mat of fleshy, green leaves and produces clusters of white, star-shaped flowers during the summer months, which are moderately showy and attract pollinators.

Thunberg’s Crassula is valued for its drought tolerance and ease of maintenance, making it an excellent choice for rock gardens, succulent collections, and as ground cover in xeriscaped areas. It is also suitable for container planting, where its water needs can be easily managed. This succulent requires minimal water once established and thrives in well-draining sandy or loamy soils. It prefers full sun to part shade, with some protection from the hottest afternoon sun in warmer climates. While generally pest-free, it can be susceptible to mealybugs and fungal diseases if overwatered or in poor-draining soil. Thunberg’s Crassula is not known for aggressive roots or significant disease issues, but care should be taken to avoid overwatering to prevent root rot.CC BY-SA 4.0
