Euphorbia stenoclada, better known as Samanta, is an emblematic plant of Madagascar. Particularly prized in botanical gardens, it stands out for its sculptural appearance and exceptional resilience. Native to the island’s arid regions, this euphorbia is characterized by its spiny, architecturally shaped branches and minimalist foliage. Its unique aesthetic is perfectly suited to dry environments.
Growing naturally in coastal and semi-desert areas, Euphorbia stenoclada or Samanta often reaches heights of 2 to 5 meters. It then forms a dense shrub or small tree. Its silvery-grey stems and sharp spines play a protective role in its natural habitat. They deter herbivores and limit water loss. What’s more, the small, discreet but charming yellow or greenish flowers appear mainly in the dry season. They add a subtle touch of color to its robust appearance.
In the botanical garden of the Au Bois Vert estate in Ivato, near Antananarivo, Euphorbia stenoclada attracts the attention of visitors curious to discover the endemic riches of Madagascar. Indeed, this plant perfectly embodies the spirit of sustainability and adaptation to harsh conditions. This aspect resonates with the ecological principles promoted by the hotel and lodge.
Its presence in the botanical garden is not limited to its aesthetic role. The Euphorbia stenoclada or Samanta also offers educational value, raising visitors’ awareness of Madagascar’s unique biodiversity and the importance of its conservation.
Plant use
uphorbia stenoclada is more than just an ornamental plant; for centuries, local populations in Madagascar have used it for its medicinal properties, its wood, and its ability to structure the landscape. Its latex, though toxic, is sometimes used in traditional practices, particularly to treat skin infections or as a natural repellent against parasites. However, handling it requires great caution due to its caustic nature. In rural areas, this euphorbia plays a vital role in the creation of living hedges, with its formidable thorns serving as an effective natural barrier to protect crops and homes. Its wood, although lightweight, is occasionally used as a construction material or fuel. In a modern context, Euphorbia stenoclada fits seamlessly into dry gardens or landscaped spaces that require little maintenance, making it an ideal choice for landscaping professionals or enthusiasts of exotic plants. At the botanical garden of the Au Bois Vert estate, it exemplifies the potential of sustainable and visually appealing vegetation suited to arid climates; by cultivating it in a carefully designed environment near Ivato, the site’s managers also promote the respect and integration of endemic species into settings such as hotels, restaurants, or lodges.
