Dypsis decaryi, commonly known as the Triangle Palm, is a unique and visually striking palm tree native to the island of Madagascar. It is named for the unusual shape of its trunk, which forms a distinct, triangular cross-section. This feature, along with its graceful, arching fronds, makes it a popular choice for tropical and subtropical landscapes around the world.
The Triangle Palm typically grows to a height of 7–15 meters (23–50 feet), with a single, smooth trunk that is often covered with leaf scars. The trunk's triangular shape is most pronounced in younger palms, becoming more cylindrical as the tree matures. The leaves are pinnate, feather-like, and grow in three distinct ranks, which further enhances the plant's triangular appearance. The fronds are a striking blue-green color, with a slight silver hue on the underside, adding to its ornamental appeal.
