Dypsis decaryi (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. It displays a single smooth upright trunk that reaches 20 feet in height. Also, it has an open crown of arching pinnate bluish-green leaves measuring 10 feet long and 3 feet wide. The petioles are brown with a whitish bloom.
Furthermore, this palm flowers continuously with inflorescences emerging from the lower leaves and bearing yellow-green blooms of both sexes on the same plant. Fruits are black and round, about 1 inch in diameter and are eaten by birds. Dypsis decaryi (Triangle Palm) thrives in well-drained soil with adequate water; it can withstand temperatures down to freezing. It responds well to regular fertilizer. These palms are propagated by seeds, which germinate in 1 -2 months. Standing alone as a specimen palm on a lawn or in groups this palm is quite breathtaking, and considered a very attractive palm for open setting; although in groups is quite appealing as well. There are more than 150 species of dypsis, all native to the indian ocean islands.
