Rhipsalis paradoxa, also known as the braided Chain Cactus, is a remarkable epiphytic plant native to Brazil. This unusual cactus is easily recognised by its long, segmented stems that drape gracefully in chain-like formations—hence its nickname, the “chain cactus.” At the Au Bois Vert botanical garden in Ivato, near Antananarivo, it draws the eye with its distinctive appearance and impressive adaptability to a variety of environments.
In its natural habitat, Rhipsalis paradoxa grows in the crevices of trees within tropical forests, thriving in humid conditions and dappled light. Its stems can grow several metres long, creating a striking visual effect as they cascade downwards. The flattened, slightly toothed segments of the stems only enhance its exotic appeal.
One of the plant’s main strengths is how easy it is to care for. It thrives in well-draining soil and prefers indirect light. Moderate but consistent watering keeps the soil lightly moist, without becoming waterlogged. During the winter months, reducing watering helps prevent root rot.
At the Au Bois Vert botanical garden, Chain Cactus plays an important role in supporting local biodiversity. It provides shelter and nourishment for various insect and bird species. Its small white flowers—mainly blooming in late winter and early spring—are followed by spherical fruits ranging in colour from white to black. These berries, reminiscent of mistletoe, add another layer of decorative interest to an already captivating plant.
Guests at the Au Bois Vert hotel or restaurant can enjoy this fascinating plant up close while soaking in the calm and beauty of the surrounding natural environment.
