Up to 3m tall, this is the biggest and smelliest flower in the world. When it blooms it releases a disgusting smell, a bit like rotting meat that can be smelled over a long distance. Since the plants tend to be a long way apart and do not flower very often, the scent is thought to be essential for attracting insects to spread their pollen.
There are a number of flowers that smell bad and they are often pollinated by flies, beetles or other insects that normally feed on dead animals.
