Crassula umbella, commonly known as the ‘Wine Cup’ succulent, is an unusual and attractive plant in the large Crassulaceae family. Native to South Africa, this rare succulent is known for its unique appearance and structural beauty. Today, I make this brief article introducing everything I know about this plant!
Crassula umbella is a perfect succulent that breaks away from the typical forms associated with this family of plants. This intriguing succulent has an unusual rosette shape that stands out in the plant world.
The leaves of Crassula umbella are stemless and grow in an upward-facing, cup-like fashion. This unique formation resembles a wine glass, earning it the nickname ‘Wine Cup.’ The leaves are a rich, bright green, sometimes featuring a hint of red along their edges, particularly when exposed to plenty of bright light.
The flowers of Crassula umbella are one of its most exciting features. They emerge from the center of the leaf rosette on 10-inch tall flower stalks. The flowers bloom in dense clusters and are striking yellow to orange. These blooms typically appear in winter, providing a splash of vibrant color during the colder months.

Caring For Crassula Umbella
- Watering: The Crassula umbella has modest watering needs typical of succulents. During the growing season, it prefers deep watering. While the plant is dormant in winter, watering should be significantly reduced. Overwatering can kill the plant, leading to root rot, a common issue with succulents. It’s hard to revive a succulent from root rot.
- Soil: A well-draining soil mix is critical for the healthy growth of Crassula umbella. A standard cactus or succulent mix is suitable. Regular potting soil, coarse sand, and perlite or pumice can be used for those who prefer to make their mix.
- Light: This succulent enjoys bright, indirect light, though it can tolerate some shade. However, plenty of light is beneficial for optimal growth and leaf coloration. Direct, intense sunlight can cause the leaves to scorch, so a balance is necessary.
- Temperature: Crassula umbella prefers warm climates and is not frost-tolerant. It’s vital to protect this plant from freezing temperatures. Growing this plant indoors or in a greenhouse is advisable during cold winters.
- Fertilizer: While not strictly necessary, providing your ‘Wine Cup’ succulent with a diluted cactus or succulent fertilizer in the growing season can encourage growth and boost flowering.
- Propagating Crassula umbella can be achieved from seeds or cuttings. If propagating from cuttings, it’s crucial to let the cut surface dry out and form a callus before planting it in well-draining soil. This process helps to prevent potential fungal infection and promotes better root development.
- Pests and Diseases: Crassula umbella can be susceptible to succulent pests such as mealybugs and spider mites. Regular inspection and early treatment are essential for maintaining the plant’s health. In the case of infestation, insecticidal soap or neem oil can eliminate pests.
- Repotting: Repotting should be done every two years to refresh the soil and give the plant more room to grow. It’s an opportunity to check the roots for any signs of disease and to remove dead leaves or stems.
