What is Euphorbia Stellata?

Euphorbia stellata, also known as the star cactus or Medusoid euphorbia, is a small geophytic succulent that belongs to the Euphorbiaceae family. This unique plant is characterized by its tufted, prostrate branches that resemble stars. The dark green branches are adorned with feathery whitish markings, giving them a distinct and mesmerizing appearance. Euphorbia stellata branches have two ribs and can grow up to 6 inches in length and 0.6 inches in width. They also feature winged margins and sinuate teeth, adding to their visual appeal.

During the late spring and early summer, Euphorbia stellata produces greenish-yellow flowers, further enhancing its beauty. These flowers, which belong to the Medusoid Euphorbias group, add a delicate touch to the plant’s overall appearance.

Euphorbia Stellata Care Guide

To ensure that your Euphorbia stellata thrives and continues to amaze you with its beauty, proper care is essential. Here are some care tips to keep in mind:

Sun Exposure & Light Requirements

Euphorbia stellata thrives in full sun to partial shade conditions. It requires at least six hours of direct sunlight daily to maintain its vibrant color and overall health. When grown indoors, place your Euphorbia stellata in a location that receives ample sunlight or consider supplementing with artificial grow lights.

Watering Requirements

As a succulent, Euphorbia stellata prefers infrequent watering. Allow the soil to dry out completely before watering, and make sure the pot has proper drainage to prevent waterlogging. A good rule of thumb is to wait until about one-third of the topsoil has dried before watering again.

Soil Requirements

Euphorbia stellata thrives in well-draining, porous soil. Ideally, use a cactus soil mix or a potting mix that consists mostly of sand to allow excess water to drain away quickly. Avoid using heavy or clay-based soils, as they can retain too much moisture and lead to root rot.

Temperatures and Humidity

Euphorbia stellata prefers temperatures between 18°C and 27°C (64°F – 80°F) and humidity levels around 40% to 60%. Avoid exposing the plant to extreme temperature fluctuations or prolonged periods of high humidity. Proper ventilation is also crucial to prevent the onset of fungal and bacterial diseases.


Euphorbia stellata does not require frequent fertilization. Apply a half-strength liquid fertilizer, diluted according to the manufacturer’s instructions, every month or two. However, avoid fertilizing during hot weather to prevent leaf burning. Remember to always follow the recommended guidelines for your specific fertilizer.

Potting and Repotting

Euphorbia stellata should be repotted every two to three years or when it outgrows its current container. When choosing a pot, ensure it has enough room for the plant’s root growth and doesn’t dry out too quickly. During the repotting process, be cautious of the plant’s milky white sap, as it can cause skin irritation. It’s recommended to wear gloves or use tools when handling Euphorbia stellata.


Periodic pruning is necessary to maintain the health and appearance of Euphorbia stellata. Remove any dead or dying leaves, lower stems without live roots, and any discolored or infected leaves. Pruning can also help shape the plant and promote branching for a more compact and aesthetically pleasing look.

Pests and Diseases

Euphorbia stellata is generally resistant to pests and diseases. However, occasional infestations of aphids, mealybugs, or spider mites may occur. Treat any pest issues promptly with insecticidal soap spray or neem oil. Additionally, ensure proper drainage to prevent the development of root rot, a common issue in succulents. If root rot occurs, it’s essential to act quickly to save the plant’s life.

Winter Care

During colder months, protect Euphorbia stellata from frost and desiccation by bringing it indoors or providing insulation. Covering the plant with fabric or using a frost cloth can help provide additional protection from freezing temperatures. It’s crucial to adjust watering frequency during winter to accommodate the plant’s dormancy period.


Euphorbia stellata can be propagated through various methods, including stem cuttings, offsets, or seeds. Stem cuttings should be allowed to callous for a few days before planting in a well-draining soil mix. Leaf cuttings can also be used, where a healthy leaf is placed in the soil with the cut end inserted to encourage root development. For offsets, simply divide the plant into smaller sections, ensuring each section has some roots attached, and pot them in well-draining soil. It’s important to note that Euphorbia stellata produces a milky sap that can cause skin irritation, so handle the plant with care during propagation.


Euphorbia stellata, like many other euphorbia species, contains a milky sap that can be toxic to pets and humans if ingested. It’s essential to keep the plant out of reach of curious children and pets. If you come into contact with the sap, wash the affected area with water and seek medical attention if any signs of an allergic reaction occur.


Euphorbia stellata, with its unique branching pattern and star-like appearance, is undoubtedly a standout house plant. With proper care and attention to its specific needs, you can enjoy the beauty of Euphorbia stellata for years to come. Whether you choose to grow it indoors or outdoors, its captivating charm is sure to impress both you and your guests. So, why not add a touch of celestial beauty to your plant collection with Euphorbia stellata?
