Roystonea regia, commonly known as the royal palm, is a large, majestic palm tree native to the Caribbean, Mexico, Central America, and Florida, widely planted as an ornamental tree in the tropics and subtropics. It is characterized by a tall, smooth, grey trunk with a distinctive green crownshaft, topped by a crown of large, feather-like leaves and showy white flowers that produce fruit. Valued for its beauty and hurricane resistance, it's used as a specimen or street tree, thriving in full sun and moist, well-drained soils.
