The corpse flower (amorphophallus titanum) is an enormous and rare flower. It gets its name from the putrid stench it emits. A corpse flower blooms no more frequently than once every 3 years and can sometimes go decades between blooms. Once in bloom, a corpse flower may remain in bloom for only 24 to 48 hours and then it quickly collapses. This particular corpse flower at the United States Botanic Garden is 7 feet and 4 inches tall.
