Sumatran Century Flower

The Sumatran Century Flower is a flower that blooms every 100 years. It is one of the attractions at Springfield Botanical Gardens.

History
The Sumatran Century Flower was about to bloom, and the Simpson family along with many other residents of Springfield were at the Botanical Gardens to witness the event. When the flower bloomed, the assembled townspeople were at first awed by the sight. Immediately after it bloomed, however, the flower emitted a noxious gas that had an extremely foul smell and killed every other plant that was nearby. The gathering turned into mass chaos (and caused a traffic jam) as everyone ran to their vehicles and drove away to flee the stench. Krusty the Clown dove into a manure pile to escape the flower's odor and found that the manure smelled "mildly better".

Behind the Laughter
The Sumatran Century Flower bears a strong resemblance to the real-life Sumatran flower , which is better known as the "corpse flower" due to the rotting-flesh smell it gives off when it blooms. The corpse flower, however, blooms on an annual cycle.
