It’s stinky and it’s huge—and it’s about to bloom.

The world’s tallest flower is set to bloom this week.

Its scientific name is The Amorphophallus titanium (Titan Arum for short).

The extremely rare flower is at the Niagara Parks’ Floral Showhouse, near the Canadian Horseshoe Falls in Ontario. When it blooms, it will be the 22nd of its kind to bloom in a botanical garden.

Titan Arum is also known as the corpse flower. That’s because of the stinky odour it gives off. It smells like rotting meat.

Its horrible smell helps the flower attract insects that it needs for pollination. (Lots of insects are attracted to rotting meat.)

Titan arum normally grows in the rainforests of Sumatra.

However, this one—and another one that is also growing and will bloom after the first one—was donated by a man who lives in New Hampshire, U.S.
