Why would it be advantageous for a flower to stink like a corpse? Learn more about the Rafflesia, better known as the corpse flower.
Rafflesia is a very strange flower: it has no petals or leaves, but it doesn't need any. It feeds on other plants instead.
It blooms just once every five years, and when fully blossomed it is the largest flower in the world at over 3 feet across!
When the Rafflesia blooms, it unleashes an unholy odor, just like rotting flesh. Hence the name: Corpse Flower.
It even looks like a carcass: its lumpy and mottled surface, and tough skin is intentionally un-flower-like.
Why would a flower do this? The same reason other flowers look and smell the way they do: they want to get pollinated!
