Meat-Stinking Giant Flower Has A Delectable Aroma For Pollinators
The Titan Arum, more commonly known as the ‘Corpse Flower’ is famous for its repulsive meat smell. Designed to repel humans, in contrast pollinators find the putrid aromas irresistible in the plant’s native environment. The Corpse Flower Titan Arum lives deep inside of Sumatra’s imperilled rainforests. endangered by palm oil and mining deforestation. Now researchers have gained greater insight into how the plant warms itself up before blooming – known as thermogenesis and have discovered a new compound called ‘putrescine’ which gives the plant its strong aroma.

The Titan Arum, more commonly known as the ‘Corpse Flower’, is famous for its repulsive meat smell. While designed to repel humans, this putrid aroma irresistibly attracts pollinators in its native environment—the imperilled rainforests of Sumatra, now under threat from palm oil plantations and mining activities. Researchers have recently uncovered how the plant generates heat before blooming, a process known as thermogenesis, and have identified a new compound called ‘putrescine’, which contributes to its potent stench.
A study led by G. Eric Schaller, Professor of Biological Sciences at Dartmouth College, explored the genetic and biological mechanisms behind the Titan Arum’s remarkable heating and scent production. The research relied on tissue samples from ‘Morphy’, Dartmouth’s 21-year-old Corpse Flower, to analyse RNA sequences. This allowed scientists to pinpoint which genes are active during the phases of heating and scent release.
The Titan Arum is not a single flower but a cluster of tiny flowers hidden within a massive central stalk, known as the spadix, which can reach up to 12 feet in height. It blooms rarely—typically once every 5 to 7 years—and only for a brief period. “The blooms are rare and also short-lived, so we only get a small window to study these phenomena,” Schaller explains.
During blooming, the spadix heats up, raising its temperature by as much as 20 degrees Fahrenheit above the surrounding air. This thermogenic phase coincides with the emission of its signature scent, a mixture of sulphur-based compounds designed to attract flies and carrion beetles, which play a vital role in the plant’s pollination.
The RNA analysis revealed that genes associated with alternative oxidases—plant equivalents of animal uncoupling proteins—are highly active during the heating phase, especially in the spadix’s appendix. Additionally, genes involved in sulphur transport and metabolism were expressed, driving the production of the odour. Among these compounds, researchers identified putrescine, an organic chemical not previously recognised as part of the Corpse Flower’s scent profile.
This research sheds light on the evolutionary adaptations of the Titan Arum while highlighting the urgent need to conserve its natural habitat. Protecting the rainforests of Sumatra from deforestation caused by palm oil cultivation and mining is critical for the survival of this extraordinary species. By choosing to #BoycottPalmOil and supporting campaigns such as #Boycott4Wildlife every time you shop, individuals can help safeguard the delicate ecosystems these rare flowers depend on, ensuring they continue to thrive for generations to come.

3. Supermarket sleuthing: Next time you’re in the supermarket, take photos of products containing palm oil. Share these to social media along with the hashtags to call out the greenwashing and ecocide of the brands who use palm oil. You can also take photos of palm oil free products and congratulate brands when they go palm oil free.

#corpseflowerIt opened over about 4 hours. Lights are now on 24/7 while it flowers, and it is open till midnight for visitors.

UPDATE Oops, altho promising 24hr illumination, seems they turned the lights off at midnight.
Tomorrow they will open from 7:30am till midday and again from 7pm till midnight, due to the extreme heat. Check current announcements on website or live stream for any updates.
Corpse Flower is blooming!
NO growth since yesterday. Does this mean that the opening is imminent?
Not flowering yet.
I am surprised how few people walking past pay much attention to it. It may not have opened yet, but there are less than 1000 in the wild.
It continues to grow each day, it seems a couple of cm each day.
There's a Corpse Flower in Adelaide that's ready to bloom.
It's name is Smellanie.
