The Euphorbia cotinifolia, commonly known as the Smoketree Spurge, is a striking ornamental plant with vibrant purple foliage that naturally draws attention in any botanical garden. Native to the tropical regions of Central and South America, this perennial belongs to the Euphorbiaceae family. Its lush leaves and slender form, which can reach between 4 and 6 metres in optimal conditions, make it a remarkable feature in the landscape.
At the botanical garden Au Bois Vert, located near Ivato in Antananarivo, the Euphorbia cotinifolia blends seamlessly into the tropical surroundings, adding a bold splash of colour that contrasts beautifully with the surrounding greenery. Its rounded leaves, reminiscent of those of the Cotinus (commonly known as the smoke tree), are the reason behind its name. This plant thrives in well-drained, nutrient-rich soil and enjoys full sunlight to fully develop its intense hues. However, in warmer climates, it can also tolerate partial shade.
During spring and summer, the Smoketree Spurge produces small, delicate cream-coloured flowers, subtly enhancing its appeal without overshadowing its striking foliage. Hardy and heat-resistant, this low-maintenance plant becomes self-sufficient once established. However, it is sensitive to frost, which restricts its cultivation to milder or temperate climates.
For visitors to the Botanical Garden, this plant serves as a captivating focal point while also showcasing the botanical diversity of the Au Bois Vert hotel-restaurant. Whether staying at the lodge or simply enjoying a peaceful break, discovering the Euphorbia cotinifolia adds an enriching touch to the experience in this lush and tranquil setting.
