The Citrus sinensis, commonly known as the orange tree, is a true emblem of Mediterranean and tropical gardens. A member of the Rutaceae family, it is cherished not only for its sweet, juicy fruit but also for its ornamental value among botany enthusiasts. With its deep green evergreen leaves and fragrant white blossoms, it brings a sense of beauty and freshness to any setting – including the Au Bois Vert botanical garden, located near Ivato and Antananarivo.
Native to Southeast Asia, particularly China and India, the orange tree has spread across the globe thanks to its remarkable adaptability. Today, it thrives in subtropical and tropical regions, where warm, sunny climates support its growth. Typically reaching between 5 and 8 metres in height, it can remain more compact when grown domestically. Its long lifespan, spanning several decades, makes it a lasting feature in green spaces such as eco-lodges and hotels.
The orange tree blossoms in spring, filling the air with a sweet, heady fragrance. Its nectar-rich flowers attract bees, playing a vital role in supporting local biodiversity. Once pollinated, these blossoms develop into the much-loved fruit: the orange. Visitors to our botanical garden can admire healthy, well-cared-for specimens, displayed to highlight their natural charm and vitality.
Plant use
The orange tree is valued not only for its beauty but also for its many uses. Its fruit, rich in vitamin C and antioxidants, is among the most widely consumed in the world. Oranges are enjoyed fresh or used in juices, jams, and baked goods. In the kitchens of lodges and restaurants in Ivato and Antananarivo, they frequently feature as a flavourful addition to both local and international dishes. But the orange tree’s benefits go well beyond its fruit. Its blossoms are distilled to produce neroli essential oil, a prized ingredient in perfumery and aromatherapy. The leaves and bark can be used to make soothing herbal teas or as natural insect repellents. Beyond its culinary and therapeutic qualities, the orange tree also plays an important ecological role. In a botanical garden, it helps to create a pleasant microclimate and provides a haven for many species, especially birds and pollinating insects. If you're staying at our hotel or dining in our restaurant near Antananarivo, take a moment to stroll among these beautiful fruit trees and let yourself be charmed by their timeless elegance.
