Roystonea

10 species. The genus Roystonea is found throughout the Caribbean basin, with most species native to the Greater Antilles. Roystonea regia, the royal palm, is the best known palm in Miami landscapes. It is easy to grow with little care, and is the preferred species for palm-lined avenues. Majestic stands of wild royal palms can be found in Everglades National Park. We have found all species of this genus to grow well at Fairchild, but the massive Roystonea oleracea and graceful Roystonea princeps are favorite elements of our landscapes.
