Corpse Flower in Bloom in Belgium; Hold Your Nose! Tourists are lining up in Belgium for the chance to visit a huge, foul-smelling plant. The national botanical garden was staying open until dusk for a second day Tuesday to give as many people as possible a view of the titan arum - also known as the corpse flower - that's towering over the visitors. At the heart of the flower a huge column rises upward to the sky and is responsible for the smell that resembles a decomposing animal. The rare Sumatran plant has now flowered three times since 2008, a feat in itself. At its height this year, it measured 2.44 meters (8 feet). It only flowers for three days, and is expected to wane on Wednesday.
