The Euphorbia umbellata, commonly known as the Marbled Spurge, is a fascinating ornamental plant, renowned for its resilience and exotic beauty. Native to tropical regions of Africa, it is characterised by its bright green foliage adorned with red or brown veins, as well as its milky sap, a distinctive feature of euphorbias. Primarily cultivated as a houseplant in temperate climates, it can also thrive outdoors in warm regions, such as those surrounding the Au Bois Vert botanical garden in Ivato, near Antananarivo.
In its natural habitat, the Marbled Spurge flourishes in sunny or partially shaded areas with well-drained soil. This perennial plant can grow up to 1.5 metres tall under optimal conditions, making it a popular choice for decorative plant arrangements. Although its flowering is subtle, it adds a delicate touch with small blooms clustered in inflorescences, often accompanied by reddish-hued bracts.
At the Au Bois Vert botanical garden, this plant enhances local biodiversity and captivates visitors to the hotel and lodge, particularly due to its easy maintenance and timeless aesthetic. With flowering occurring mainly in spring and summer, it draws the attention of exotic plant enthusiasts and botanists seeking unique species.
Plant use
The Euphorbia umbellata is not only admired for its beauty but also valued for its remarkable properties, making it a highly versatile plant. In its native regions, certain parts of the plant have traditionally been used for medicinal purposes. Its sap, though toxic if handled improperly, is utilised in local pharmacopoeia for its antiseptic and healing properties. However, any use requires great caution and in-depth knowledge to avoid adverse effects. In ornamental landscaping, the Marbled Spurge is often chosen to enhance outdoor spaces in hotels, restaurants, and lodges, such as those at Au Bois Vert in Ivato. Its resilience to drought and low maintenance needs make it an ideal plant for environments where water management is crucial. It also adds an exotic touch that enhances tropical gardens while being resistant to common pests. Thanks to its decorative and functional qualities, this plant integrates seamlessly into green spaces, particularly botanical gardens, where it complements collections of tropical species. Beyond its aesthetic appeal, it raises awareness among visitors about the richness of African flora and the importance of its conservation. The team at the Antananarivo Botanical Garden ensures its proper care, allowing everyone to appreciate its benefits while educating on its uses and necessary precautions.
