Voodoo lilies or corpse flowers don’t just sound ominous; they also look and even smell the part. Sauromatum venosum, Dracunculus vulgaris, and various Amorphophallus species are all members of the arum family and have been called voodoo lilies. They produce large, bizarre “flowers” that emerge directly from the ground and open up to reveal dried blood-colored spathes and briefly-smelly, long, spiky spadixes. These plants seem to have been designed with Halloween in mind, except for one thing—they bloom in the spring. Even so, they are worth planting to appreciate their gothic appeal when the time is right.
