Titan Arums (Amorphophallus titanum) have flowers that can be up to 3 metres high and 3 metres in circumference.
Giles Palmer, Curator of Plants and Gardens at Paignton Zoo, said: “There are about 100 collections in the world where you can see this plant – they can go for years between flowerings, so it’s not a common sight.”
The plant - from the rainforests of Sumatra and a member of the Arum family - is classed as Vulnerable on the IUCN Red List of Threatened Plants. It has one of the largest flowers in the world; the bloom – correctly, an inflorescence – is green on the outside and bright red inside, with ribbed sides and a frilled edge. Due to its odour – said to be like rotting meat – it’s known as a carrion flower, and has been dubbed corpse flower or corpse plant. It emits the strong smell at night to attract pollinators.
