The elaborate network of air-filled veins on the leaf’s underside give it the structural strength to support almost 90 pounds on its surface.Photo:Jonathan Singer

Then the plant sends up a single leaf and 10-foot stalk pictured here. The plant stores energy for producing the bloom in an underground tuber that can weigh nearly 100 pounds.Photo:Jonathan Singer
