Description: Queen Palm is a popular ornamental tree in the U.S. native to South America and has become naturalized to some extent in Florida. This medium-sized palm matures quickly, growing up to 49′. It has a slender straight, smooth grey trunk that is 1′-2′ wide. Its high canopy is comprised of arching leaf fronds. Each pinnate leaf has as many as 494 pinnae (leaflets), although 300 is most common. Each pinna is approximately 18″ long and 1’–2″ wide. Creamy yellow flowers appear in spring and summer, growing in panicled clusters. Later its edible oval fruit appears. Each is 1″-1.5″ long and consists of a hard nut surrounded by a thin layer of fibrous flesh that is orange and sticky when ripe.
