Baccharis salicifolia, commonly known as mule fat, is a perennial plant belonging to the Asteraceae family. Native to the tropical and subtropical regions of the Americas, it thrives particularly in wetland areas across the United States, Mexico, Central America, and South America. It adapts easily to a variety of habitats, from coastal plains to mountainous regions at altitudes of up to 2,500 metres.
This plant is characterised by its woody stems, which can grow up to four metres tall, and its narrow, elongated leaves resembling those of a willow—hence its scientific name, salicifolia, meaning ‘willow-leaved’. Its white or cream-coloured flowers, clustered in dense groups, typically bloom between summer and autumn. Baccharis salicifolia creates a striking visual display, making it an excellent choice for biodiversity enthusiasts in a botanical garden.
Beyond its aesthetic appeal, Baccharis salicifolia, or mule fat, plays an important ecological role. It provides shelter and a food source for various pollinating insects, particularly bees and butterflies. Thanks to its ability to stabilise soil and withstand challenging conditions, it is often used in environmental restoration projects. Visitors to the Au Bois Vert botanical garden, near their lodge in Ivato, will have the opportunity to admire this remarkable plant, which showcases both resilience and beauty.
Plant use
Baccharis salicifolia stands out for its numerous traditional and modern uses. For centuries, Indigenous communities across the Americas have utilised it for its medicinal properties. Its leaves, rich in bioactive compounds, are used to prepare herbal infusions that help relieve pain, reduce inflammation, and treat digestive disorders. These medicinal benefits continue to be the subject of scientific research, aiming to develop natural treatments. In landscaping, this plant plays a crucial role in creating sustainable green spaces. Thanks to its resilience in poor soils and its adaptability to diverse climates, it integrates seamlessly into botanical gardens, urban areas, and conservation sites. At the Au Bois Vert Botanical Garden, it enhances the pathways while reinforcing the site's ecological identity. Commonly known as mule fat, this plant is also an excellent nectar source for bees, making it essential for supporting pollinator populations. Its flowers provide abundant nectar, boosting honey production—a valuable asset for local beekeepers. Additionally, cultivating Baccharis salicifolia helps preserve natural resources in fragile ecosystems. A visit to the Au Bois Vert Botanical Garden, near the hotel and restaurant, offers a unique opportunity to see how this remarkable plant contributes to conservation efforts and environmental education.
