If you want to grow an exotic-looking plant in your garden, try Amorphophallus rivieri, also known by another scientific name, Amorphophallus konja, and commonly called devil's tongue and voodoo lily. When this fleshy, frost-tender perennial blooms, it creates a visually striking and smelly statement in the garden. A single, deep-purple petal, called a spathe, surrounds the 3-foot tall flower stalk that is on the plant's 4- to 6-foot tall stalk. The flower's aroma is like the odor of rotting meat. The scent attracts flies that pollinate the flower. Voodoo lily is hardy in U.S. Department of Agriculture plant hardiness zones 6 through 10. Its leaf and flower stalk are frost-tender and die back from the first freeze, but its tuber and roots survive under soil within the plant's hardiness zone range.
