This plant is causing a stink at the National Botanic Garden of Wales in Carmarthenshire.
It's known as the Voodoo Lily, but its real name is Amorphophallus Konjac.
This year, it's bloomed for the first time. This means it's giving off a yucky smell similar to rotting meat, which is meant to attract flies.
Staff at the centre are hoping that it will also bring in visitors who are curious to check out this marvel of the natural world.
"Our gardener in charge of the tropical house says it will be stinking the house out by the end of the day," said a garden spokesman.
"We're hoping the smell will last until the weekend so as many people as possible can experience it."
The plant goes by many names - including Devil's Tongue and Elephant Yam, although Voodoo Lily is the most popular.
This one arrived at its new home in Wales about a year ago, although the plant is native to hot parts of Asia.
