Zones

A rare and visually arresting member of the Araceae family, Alocasia Boa is prized for its massive, serrated leaves and marbled stems. Native to the humid lowlands of Papua New Guinea, this tropical perennial makes a bold statement with its zigzag-edged foliage and robust, upright form. Its serpentine spathe coloration inspired the name “Boa,” and it’s considered morphologically intermediate between Alocasia hollrungii and Alocasia brancifolia.
