The Triangle palm is an easy-to-identify pinnate-leafed palm. Due to the unusual triangular form made by the leaf bases on the trunk, it’s easy to spot. Accordingly, the triangle palm is a moderate to large palm. The beauty of this palm is quite stunning when grown alone or in groups on a lawn; however, it is equally attractive when grown in groups. In well-drained soil with sufficient water, the Triangle Palm Tree thrives. It also responds well to fertilizer on a regular basis.
