Scientific Name
Orbea variegata (L.) Haw.
Previously classified as Stapelia variegata, this species belongs to the Apocynaceae family. The reclassification to the genus Orbea reflects updated botanical understanding.
Common Name(s)
Starfish Plant, Starfish Cactus, Carrion Flower, Toad Cactus, Toad Plant
Origin
Native to the coastal belt of the Western Cape, South Africa, where it thrives in well-drained soils and sunny conditions.
Light
Prefers bright, indirect light. It can tolerate some direct sunlight but should be protected from intense midday sun to prevent scorching. Inadequate light may lead to leggy growth and reduced flowering.
Water
As a succulent, it requires minimal watering. Allow the soil to dry out completely between waterings. Overwatering can lead to root rot. During the winter months, reduce watering frequency as the plant’s growth slows.
Humidity
Adapted to arid environments, it prefers low humidity levels. Ensure good air circulation to prevent fungal issues, especially in more humid climates.
Soil
Plant in a well-draining cactus or succulent potting mix. Adding perlite or coarse sand can enhance drainage. Repotting every 2–3 years in the spring helps refresh the soil and provides space for growth.
Food
Fertilize sparingly during the active growing season (spring and summer) with a diluted, balanced, water-soluble fertilizer formulated for succulents. Avoid fertilizing during the dormant winter period.
Temperature
Thrives in temperatures between 18–26°C. It is not frost-tolerant and should be protected from temperatures below 10°C. In cooler climates, it is best grown indoors or in a greenhouse.
Pet-safe
Non-toxic to pets and humans, making it a safe choice for households with animals.
Sprouts Top Tips
To encourage blooming, provide ample light and avoid overwatering. The distinctive flowers emit a faint carrion-like scent, attracting pollinators like flies. While the odor is generally mild, placing the plant in a well-ventilated area can minimize any discomfort.
Extras
The Starfish Plant may produce seed pods after flowering. If propagation is desired, seeds can be collected and sown in a suitable succulent mix. Alternatively, stem cuttings can be taken during the growing season for propagation.
Did You Know?
Despite its common names like “Starfish Cactus” and “Carrion Flower,” Orbea variegata is not a true cactus. Its star-shaped flowers, often speckled with maroon, can reach up to 8 cm in diameter and may have a faint carrion smell to attract pollinating insects.
