Rafflesia produces one of the largest single flowers in the world and smells like rotting meat.

The longer version

This plant has no leaves, stem, or roots of its own. It lives inside a tropical vine as a parasite, drawing everything it needs from the host, and only the flower ever appears outside, pushing through the bark when it is ready.

The smell is the point. Flies that normally lay eggs on decaying matter are drawn to the odour and the mottled colouring, and while they search they pick up or deposit pollen. Because blooms are rare, scattered, and short-lived, attracting a visitor that travels a long way matters more than attracting many. The flower itself can reach a striking size, even though the rest of the organism stays invisible.
