The triangle Palm is one of the most unique palms in the world. The blue/grey feathery leaves are keeled and arranged in three ranks, forming three distinct sides or plains. The fronds are very upright, with a slight arch at the tip. It is native to Madagascar. It can get to about 15 meters (50 feet), although since it is relatively new to cultivation, is rarely seen anywhere near that size. The leaves, about 4.6 meters (15 feet) long, point almost upright from the trunk, but then arch gracefully about 1 meter (3 feet) from the tip. They are grey-green in color, pinnate, with a brown petiole covered in a whitish bloom. The branched inflorescence comes from between the lower leaves, and bears yellow to green flowers. These later produce round black fruit about 25 mm (1 inch) in diameter. This spectacular palm makes an excellent specimen plant, and should be grown in the open without anything to obscure its unusual shape. It prefers full sun, and regular watering, however, it can stand occasional dryness and semi-shade. Will do well in areas that may receive frost occasionally. Drought tolerant once established. A very fast grower once established. Will do well in areas that may receive frost occasionally. It is also a very good container plant for a patio or large courtyard.
