A rare, exotic tropical plant known for its putrid bouquet is set to bloom under the dome at Bloedel Conservatory in Queen Elizabeth Park.

Titan arum or corpse flower is the largest flower on earth and is notorious for unleashing the smell of rotten flesh when it blooms!

Titan arum blooms are very rare and unpredictable. Most plants take seven to ten years to store enough energy to bloom for the first time. Our titan arum is approximately six-years-old and almost ready to bloom.

It will be the first to bloom publicly in BC

Horticulturists noticed a 11 inch spongy flower bud formed on Thursday, June 21 and by July 11 the bud exceeded five feet in height. 

Once the plant blooms, Bloedel Conservatory will extend its hours to 7am - 11pm for a two-day “smell it while you can” experience!

The titan arum life cycle

The titan arum (Amorphophallus titanum)also known as corpse flower, is native to rainforests on the island of Sumatra, Indonesia. It has the largest known corm in the world. The corm can grow up to 200 pounds!

Each year, it produces a leaf, reaching up to 15 feet, to absorb energy from the sun. Once the corm has enough energy to produce a flower bud and attempt to reproduce, a visual event unfolds.

Its enormous flower spike, reaching up to 12 feet, is the largest flower structure in the plant kingdom. The flower spike is wrapped with a frilly, modified leaf called a spathe.

When the titan is ready to bloom, the spathe unfolds, exposing small flowers that bloom in rings around its base that release scent molecules to signal their readiness for fertilization.

Why it's also called corpse flower

When the titan arum blooms, it emits a powerful stench similar to rancid or rotten meat. The scent and the deep-red flesh color of the open spathe, attracts pollinator insects that feed on dead animals.

During full bloom, the spadix self-heats to approximately human body temperature, which helps disseminate these odor particles.
