Copernicia macroglossa
Common Names Cuban Petticoat Palm, Jata Palm, Jata de Guanabacoa
Zones 9B–11
A striking fan palm endemic to western and central Cuba, Copernicia macroglossa is famed for its persistent skirt of dead leaves—its “petticoat”—and its upright, circular foliage. Native to serpentine soils, it thrives in blazing sun and poor substrates, making it ideal for dry tropical gardens and collectors seeking bold form and botanical curiosity.
