Lake Worth Beach bills itself as "Where the Tropics Begin." Many tropical plants grow in the city; among the more prominent examples are mahogany, royal poinciana and many species of palm, including coconut palm. African tulip tree, avocado and many species of eucalyptus may also be found, although they are on the city's list of trees to avoid. Temperate-zone trees native to Lake Worth Beach or Palm Beach County include American elm, live oak, red maple, red mulberry, and slash pine. Species grown south of their native areas include American sweetgum, Shumard oak, and tulip tree.
