The Langsdorffia hypogaea or vampire plant is a rare parasitic plant that lives in forests and savannas in Central and South America, Madagascar, and Papa New Guinea, and produces bright red flowers that mark its feeding zone.
The four different species of Langsdorffia currently known are types of holoparasitic plants, which means that they do not photosynthesize. Instead, they use subterranean suckers in the form of tentacles. to take nutrients from the roots of many different plant species, relying solely on their hosts to survive.
Lack of chlorophyll results in a blood-red flower that reminds us more of an ocean coral than of a forest floor plant. Although their specialty is slowly absorbing nutrients from other plants, they do not pose any harm to humans.
