The Eucalyptus gunnii, commonly known as the cider gum, is a tree native to the mountainous regions of Tasmania, Australia. This majestic species, belonging to the Myrtaceae family, is particularly striking due to its silvery-blue foliage, which remains attractive throughout the year. In temperate climates, it adapts exceptionally well and can grow to heights of between 10 and 25 metres. Its juvenile leaves, round and slightly waxy, gradually become more elongated and lance-shaped as the tree matures, adding a touch of elegance to any botanical garden.
At Au Bois Vert, the cider gum is a true star among the green spaces of Ivato, near Antananarivo. It creates an atmosphere that is both exotic and refreshing. Beyond its aesthetic appeal, it also produces an essential oil renowned for its beneficial properties and appreciated worldwide. As such, this tree is an excellent choice for those wishing to encourage biodiversity in their botanical gardens, as its delicate white flowers, which typically bloom in autumn, attract bees and birds.
The cider gum thrives in a variety of soil types, provided they are well-drained. Thanks to its rapid growth and evergreen foliage, it is an ideal candidate for enhancing the landscape of a hotel or lodge, such as Au Bois Vert. In Ivato, it flourishes in high-altitude gardens, benefiting from a relatively mild climate. However, regular pruning is recommended to control its growth and maintain its compact and attractive shape.
Plant use
The Eucalyptus gunnii has a wide range of uses, both practical and ornamental. Its leaves contain an essential oil highly valued in aromatherapy and cosmetics. This oil, known for its antiseptic and decongestant properties, is used in the production of balms, soaps, and even natural cleaning products. In Madagascar, its purifying qualities are also appreciated in traditional medicine. In a botanical garden such as Au Bois Vert in Ivato, this eucalyptus brings an exceptional aesthetic appeal. Its leaves and bark, often incorporated into floral arrangements, make an elegant addition to table decorations in high-end restaurants and lodges. Furthermore, its dense wood is commonly used for outdoor projects, including the construction of fences and pergolas. Finally, the round-leaved eucalyptus plays a key ecological role. Acting as a natural air purifier, it helps improve the quality of life around hotels and restaurants in urban areas. In Antananarivo, where green spaces are becoming increasingly important, this tree is an excellent choice for combining beauty with sustainability.
