On Christmas night 2020, a gift was revealed at Mount Lofty Botanic Garden that truly stank. A gift that whiffs of rotting flesh or an extremely pungent blue cheese, depending on who you ask.
And while this might seem like an unwelcome gift, it was actually quite the opposite; it was a cherished and much photographed delight. It was a blooming Corpse flower, Amorphophallus titanum, also known as Titan Arum.
The plant is originally from the Indonesian island of Sumatra, but is endangered in the wild due to deforestation.
To help conserve this remarkable species, a number of botanic gardens across the globe are fighting for its survival, working out how to grow more individuals and keep its genetic diversity strong, ready for when it can once again find a safe haven in its native land.
You may ask why it needs to smell so fetid.
Well, the potent pong attracts pollinators from far and wide – and attract them it must, because the inflorescence can only be pollinated on its first night.
This slim reproductive opportunity is made even more urgent because it can take ten years or more for a single plant to flower for the first time. And following that first bloom, it might only flower once every two to five years in cultivation - maybe longer in the wild.
So, how do you conserve such a reproductive slow burner, a panda of the plant world?
Although the plant is notoriously difficult to propagate, with lots of tender loving care from our Horticultural Curator and Titan Arum expert, Matt Coulter, this phenomenal botanical species is thriving here in our nursery.
Indeed, there was a flurry of new stinky life this summer with another plant blooming just a month after the Christmas delight, on 22 January 2021.
“This is the ninth Titan Arum to bloom at our Botanic Gardens and we learn something new every time it happens,” said Matt.
“We share our information – samples for DNA genotyping, propagation techniques, strange happenings and even corms – to other institutions across the world who are also looking out for this species. So, together, we are really making some good inroads to helping conserve Titan Arum,” he added.
From these two recent flowers, which reached a lofty 2.2 metres and 1.9 metres high respectively, Matt collected pollen which is currently chilling out in the Botanic Gardens Nursery freezer based at Mt Lofty Botanic Garden.
When the time comes, it can be used to hand pollinate a different plant, hopefully producing new and more genetically diverse seed.
We can see why Matt was on Santa’s ‘good list’!

Have you ever driven past the beautiful heritage-listed Goodman Building when passing the Garden on Hackney Road? Did you know this building was formerly the base for the Municipal Tramways Trust but now serves as the Botanic Gardens and State Herbarium administration building.
World Ocean Day is an annual celebration held on 8 June which unites and rallies the world to protect and restore our blue planet. In our latest blog, State Herbarium's Jem Barratt takes a deep dive into how its scientific work focusing on seagrasses and seaweed helps with the restoration and preservation of our ocean ecosystems.
