Alocasia × mortfontanensis is a striking rhizomatous perennial hybrid known for its dramatic foliage. It features large, arrow-shaped leaves with deeply lobed bases and prominent white or silvery veins contrasting against dark green surfaces. The plant grows upright, reaching up to 1.5 meters tall, with thick stems supporting its iconic shield-shaped leaves. Its artificial hybrid origin combines traits from Alocasia longiloba (elongated leaves) and Alocasia sanderiana (deeply scalloped leaf edges), creating a distinctive tropical appearance.
