A rare, giant corpse-scented flower is poised to blossom in all its putrid glory for the first time near Adelaide.
The endangered Titan Arum or Corpse Flower is found in the rainforests of Sumatra and can grow up to three metres high in a yellow phallic spike with a burgundy upturned skirt.
It's expected to bloom between Christmas and New Year, the Mount Lofty Botanic Garden says.
"The anticipation here is high and if it flowers, the public will have roughly 48 hours to see and smell it in all its glory - before it collapses in on itself in a heap!" horticultural curator Matt Coulter said.
The garden started growing the flower through a seed donation almost a decade ago.
"The Titan Arum is notoriously difficult to cultivate and even in optimum conditions it can take seven years for the plant to flower from seed," Mr Coulter said.
