What to Eat
Edible parts: Fruit
The palm is a fine ornamental plant and is most valuable as a specimen tree or accent plant when grown out in the open to display show its remarkable shape to best advantage. In suitable climates it blooms all year. What with its colourful flowers and fruit and shapely habit, it is unusually showy for a palm. It prefers full sun and regular watering, although it is not vulnerable to occasional dryness and partial shade. Over-watering and poor drainage are far greater hazards than drought. For example, the palm is best suited to well drained sandy soil. Dypsis decaryi does not transplant well, so it is a bad choice for commercial field growing. However, it is a fast grower once established, and its seed normally germinates within a month of being planted, so propagation by seed is a good option.
