You’ll certainly get a wow or two from your friends and family when they see -- and smell -- this plant.
Although the name Arum cornutum is no longer valid, voodoo lily (Sauromatum venosum) is a one-of-a-kind flower that needs little care to thrive. Hardy in U.S. Department of Agriculture plant hardiness zones 8 through 10, it is an interesting specimen in the garden, though you can also grow it in a container.
Grow voodoo lily outdoors in a bright area that receives approximately two to four hours of sunlight a day. It also grows best in areas with high humidity, such as a low lying area or near a pond or stream.
Water voodoo lily weekly from spring until fall with 1 inch of water. If you're growing it in a pot, water until water drips out the bottom. During the winter when the plant is dormant, keep the soil dry.
Monitor voodoo lily for spider mites, which will look like little moving dots on the plant. Spider mites leave behind fine webbing and suck the sap from leaves, turning them a yellow or reddish color. Treat infested plants with an insecticidal soap or horticultural oil, applying it to both sides of the leaves.
Cut off the foliage only when it withers in late fall or winter. It is making food all the way until this time, which helps your voodoo lily bloom next year.
Dig up the roots every three to five years after cutting back the foliage. If your voodoo lily does not die back, cut the foliage off during winter dormancy. Dry the bulb-like roots, which are called corms, for two weeks in a shady location indoors. Then, pull apart the smaller corms that are growing on the outside of the main parent corm. Plant the corms 1 to 2 inches deep, with the smaller corms planted closest to the soil’s surface. Space corms 18 to 24 inches apart. After several years, even the smallest corms should produce their own flowering plants.
