If you ever watched David Attenborough's The Private Life of Plants you would have seen footage of this amazingly large and stinky flowering plant. It only flowers for a few days and hasn't often been caught on camera. I came across this site recently in my reading and thought you might enjoy this short video.
Here's a couple of facts/sentences from the Cornell Uni site:
The basics:
The titan arum (Amorphophallus titanum) is native only to Sumatra. It blooms very infrequently (only 140 times in cultivation since 1889) and then only for one or two nights before collapsing. Until it opens, there’s no noticeable odor. After that there’s little doubt where the name “Corpse Flower” comes from.
