Largest Flower blooms in D.C.

U.S. Botanical Garden has an example of the Titan Arum, which has the largest flower of any plant and smells like rotting flesh. Evidently it is blooming now.

I'll have nightmares about this flower.

"The plant accumulates energy through its enormous leaves, some reaching greater than 18 feet tall and 15 feet in diameter .... Average recorded size of the inflorescence [flower] is about 5 feet, and the largest one is said to have been 12 ft in height! The plant lasts about 2 days at full bloom before falling into an exhausted heap."
