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

The Titan Arum, more commonly known as the âCorpse Flowerâ, is famous for its repulsive meat smell. While designed to repel humans, this putrid aroma irresistibly attracts pollinators in its native environmentâthe 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 âputrescineâ, 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 Arumâs remarkable heating and scent production. The research relied on tissue samples from âMorphyâ, Dartmouthâs 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 rarelyâtypically once every 5 to 7 yearsâand only for a brief period. âThe blooms are rare and also short-lived, so we only get a small window to study these phenomena,â 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 plantâs pollination.
The RNA analysis revealed that genes associated with alternative oxidasesâplant equivalents of animal uncoupling proteinsâare highly active during the heating phase, especially in the spadixâs 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 Flowerâs 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 youâre 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.

yay! my black-chinned hummingbird is on the feeder, it's 25 deg F right now, i had to rush out at first light to put up the sugar water & i'll swap it out every hour or so until the temperature gets to around 30 (the sugar water freezes lower & slower than pure water)
right now i can see the nectar rising as it freezes so i think i better swap it out right now since he just finished drinking 1/2

I made a full edition of my alfalfa leafcutting bee (Megachile rotundata) cutting a leaf. The alfalfa leafcutting bee is a solitary bee originally from Europe which has been spread to all continents but Antartica for agriculture. In North America it has become feral and widespread. đ§”1/2

#pollinator is an animal that moves pollen from the male anther of a flower to the female stigma of a flower.[1] This helps to bring about fertilization of the ovules in the flower by the male gametes from the pollen grains

Happy Boxing Day!
Hope you had a great Christmas if youâre celebrating and are enjoying your vacation otherwise. This is a little sneak peek of a new print I made recently of an alfalfa leaf cutter in the act of cutting its telltale half-moon cut in a leaf. I made a collection of prints to illustrate a little board book written by Lisa Jaffe about our pollinator friends in the garden. #InverteFest is hosting an anthology! đ§”

Another thing I have been exploring this year is combining other media with cyanotype. This is a unique hand made multimedia print with linocuts and cyanotype on watercolour paper (11â x 14â). On top of the cyanotype print of Canada goldenrod, I made a lino block print of the wildflower along with a monarch butterfly and an endangered Karner blue butterfly.
It and everything else is on sale this week at minouette.Etsy.com
