Apparently it blooms once every seven years from what I read. In 2014, sightings of this flower have been seen.
Check out this article from St. Louis, Missouri “Rare stinky ‘corpse flower’ blooms in St. Louis” – July 1, 2014
As you can see this flower creates quite an odor when blooming.
Also checkout this video from Loxahatchee, Florida regarding the corps flower blooming sometime this weekend, July 18 – 20, 2014. This story gives you an up close visual of the flower just before its ready to bloom.
