Roystonea oleracea - The huge, gorgeous royal palm tree is thought of by many as the world's most beautiful palm. Smooth trunks of gray to gray-white are topped with bright green crownshafts and long, luxurious, full fronds.

Soaring to heights 80 feet tall, this giant palm tree is one of the most sought-after landscape palms for elegant South Florida homes.

This is a moderately salt-tolerant palm, and it's moderately drought-tolerant as well, once it's established, though it will benefit from regular watering.
