Or rather, an Amorphophallus Titanum, a plant with a charmingly descriptive name, which can be seen at the National Botanic Garden of Belgium It's a weird-looking thing isn't it? It also smells bad. It can go about 15 years between blooming, and the flowering only lasts for three days. This is probably a good thing, because of the aforementioned smell.

Compelling to look at, though.
