A rare Amorphophallus gigas bloomed at the Brooklyn Botanic Garden for the first time since its arrival in 2018, attracting numerous visitors eager to witness the unusual event. This plant, closely related to the Amorphophallus titanum, commonly known as the corpse flower, is native to Sumatra and emits a pungent odor resembling decomposing flesh. The bloom, which consists of hundreds of male and female flowers clustered inside a towering structure, was first observed in its early stages around New Year’s Eve. The flowering process is highly sporadic, requiring several years before reoccurring. A similar phenomenon took place at the Royal Botanic Garden in Sydney, Australia, where an Amorphophallus titanum blossomed for the first time in 15 years. The plant, initially measured at 25 centimeters in December, reached 1.6 meters by late January, releasing an odor often compared to decaying organic matter.
The blooming process of Amorphophallus gigas follows a complex biological mechanism designed to attract carrion beetles and flesh flies for pollination. The plant generates heat through thermogenesis, a process that intensifies the foul odor to ensure pollinators detect the scent from a significant distance. This rare event presents both scientific and ecological significance, offering researchers valuable insights into the reproductive cycle of endangered flora. The unpredictable nature of its blooming cycle complicates conservation efforts, as propagation outside its native habitat remains challenging. Experts emphasize the importance of protecting these species in botanical institutions to mitigate the impact of habitat destruction. With climate change affecting the plant’s natural environment, botanical gardens play a crucial role in sustaining its population through controlled cultivation.
