A rare and visually arresting hybrid, Alocasia Chantrierii is known for its dark, velvety foliage and metallic sheen. Originally bred by the Chantrier brothers in France in the late 19th century, this cultivar is a cross between Alocasia cuprea and Alocasia sanderiana. Its ovate-cordate leaves feature deep green to black coloration with silvery white veins, creating a dramatic contrast that makes it a prized specimen for collectors and tropical plant enthusiasts.
