You can leave the palm fluffy and full to the ground, or thin it out to see more of the trunks. Areca palms are slow to moderate growers for sun or shade and can reach heights of 20 feet. They're wider at the top, about 10 feet in diameter, therefore allow enough room for the palm to grow a tropical canopy over nearby plants. Offered in large 20 Gallon pots or 24" boxes.
