What's In It For The Corpse Flower To Smell Like Death?

Hundreds of people flocked to the United States Botanic Garden to see (and smell) a corpse flower in full bloom.

The Amorphophallus titanum is a striking plant even before you get close enough to smell it. Its scientific name means giant, misshapen phallus and it is not hard to see why. A giant column called a spadix rises 7 feet into the air from the center of a pleated funnel.

When the plant blooms (every decade or so) that spadix actually heats up to about 90 degrees. The stench that inspires its common name — the corpse flower — comes from the putrid blend of chemicals the bloom sends into the air. The odor has notes of old fish, unwashed feet, and rotting cabbage.

This plant is pretending to be a dead animal. Why? In the wild, when insects searching for carrion are tricked into entering the corpse flower, they become unwitting aides in the plant's reproduction, carrying pollen from one corpse plant to another corpse plant nearby.

In recent years, the corpse flower's deceit has attracted another pollinator: humans. Botanical conservatories from Denver to Sydney want the stinky crowd-pleasers in their collections. And to keep the domesticated corpse flowers going, botanists must take the place of insects. They carefully collect corpse flower pollen, and send it in the mail to the next garden down the road.
