The Pandanus tectorius, also known as Screw Pine, is a distinctive tropical plant found in coastal regions of the Pacific and Indian Oceans. Often associated with idyllic landscapes, this small tree can grow up to six metres tall. Its long, linear leaves and trunk, supported by prop roots, provide it with stability. The stiff leaves, edged with spiny teeth, can reach up to 1.5 metres in length and are arranged in a spiral at the tips of the branches, giving the plant a striking, architectural appearance.
The Pandanus tectorius, or Screw Pine, produces fruit that consists of small hexagonal drupes clustered into a spherical shape. When ripe, the fruit turns an orange or reddish hue, making it highly decorative. Well adapted to saline environments and nutrient-poor soils, this plant thrives on sandy beaches and coastal areas. Furthermore, it plays a crucial role in preventing coastal erosion thanks to its extensive root system.
At the Au Bois Vert botanical garden in Ivato, near Antananarivo, the Pandanus tectorius adds an exotic touch, evoking the beauty of seaside landscapes. It enhances the visitor experience, offering a glimpse of a unique botanical setting just steps away from the hotel, restaurant, and lodge within this natural haven.
Plant use
The Pandanus tectorius is a plant with a wide range of uses, particularly in the cultures of the Pacific islands. Its long, sturdy leaves are traditionally woven into mats, baskets, hats, and rugs, supporting local craftsmanship. The fibres from the leaves are also used to make ropes. These handcrafted products, rooted in ancestral knowledge, now play a role in sustainable economies and tourism. The Screw Pine fruit is not just ornamental; in some regions, it is eaten, although its flavour varies depending on the variety. The seeds are sometimes used to produce essential oils or traditional remedies. Additionally, the aerial roots of the Pandanus contribute to local construction, serving as structural elements for roofs or shelters. At the Au Bois Vert Botanical Garden, the Pandanus tectorius perfectly illustrates the close relationship between people and nature. It also highlights how biodiversity can inspire sustainable resource management, particularly in regions like Antananarivo, where ecosystems require special care.
