In Pasadena, Calif., spectators will soon be lining up to catch a glimpse of the floats in the Rose Parade. Across the world at the Mount Lofty Botanic Garden in South Australia, however, folks are lining up for a totally different brand of floral spectacle.

There, a rare plant called the Titan arum is in bloom. This flower, which is one of the largest in the world, is also one of the smelliest. Its unique stench has led many to refer to it as the "corpse flower."

Yes. It really smells that bad. Despite this fact, or perhaps because of it, thousands of people are waiting outside of Mount Lofty to get a peek at this rare and fleeting botanical moment. One curator at the garden explained that seeing the corpse flower bloom is an unusual occurrence because "the plant is so difficult to cultivate, even in optimum conditions."

Once it does flower, its...uh...special aroma can only be experienced for 48 hours before the bloom withers. You can check out a time lapse video of the flower forming here:

The plant has been such a popular attraction that Mount Lofty has extended its hours and tweeted out advisories to warn curious visitors that they should plan to be in line for quite a while.

Dudes -- don't get confused by the popularity of the corpse flower. We're sure your lady would still rather get a plain ol' rose than one of these.
