Amorphophallus titanum (Becc.) Becc. ex Arcang.
Amorphophallus titanum holds the world record for the largest unbranched inflorescence of any plant, producing a towering burgundy-and-cream flower structure up to 10 feet tall that emits a powerful stench of rotting flesh for a single night to attract its pollinators. It symbolizes rarity, the spectacular nature of transformation, and the extraordinary power of the strange and unexpected.
Araceae (Arum family)
Unpredictable; the plant blooms only once every 7 to 10 years or more; each bloom event lasts only 24 to 48 hours

Visit Full StoreBright indirect light when growing the leaf; the inflorescence develops in the absence of the leaf and requires consistent warmth and humidity rather than direct sunlight
Consistent moisture when actively growing; the tuber must dry out completely during its regular dormant periods of 3 to 6 months
Humus-rich, Well-drained, Porous, Slightly acidic, pH 5.5–6.5
Grow in a very large container (at least 25 gallons) in humus-rich, fast-draining tropical mix with a minimum temperature of 15 degrees C (60 degrees F)
Feed heavily with a balanced fertilizer during active leaf growth; the tuber must accumulate sufficient energy to eventually produce the inflorescence
Allow the growing medium to dry completely during dormancy; never water a dormant tuber
The plant may take 7 to 10 or more years to bloom for the first time from a small tuber, and years more between subsequent blooms
Artificial pollination between two simultaneously blooming plants can produce viable seeds; this is the primary method of propagation in botanic gardens

Titan arum symbolizes rarity, spectacular transformation, and once-in-a-lifetime wonder. Its extraordinary bloom cycle and dramatic appearance make it a symbol of patience rewarded spectacularly, deep mystery, and the power of the unexpected.
The inflorescence produces a complex mixture of sulfur compounds including dimethyl disulfide and dimethyl trisulfide, along with other volatile chemicals that together replicate the smell of rotting meat and dung. This is an evolutionary strategy to attract carrion beetles and other insects that feed and breed on decomposing matter, which then unknowingly pollinate the flowers.
In the wild and in cultivation, the titan arum blooms unpredictably, typically once every 7 to 10 years or more. Each bloom lasts only 24 to 48 hours. Between blooms, the plant alternates between producing a single massive leaf for 8 to 12 months, then entering dormancy for 3 to 6 months, repeating this cycle several times before accumulating enough energy to flower.
The titan arum is native only to the tropical rainforests of Sumatra, Indonesia, where it grows on steep limestone hills. Large areas of its natural habitat have been destroyed by logging and conversion to oil palm plantations. Botanic gardens worldwide maintain living collections of titan arum plants that serve as a critical ex situ conservation resource.
Amorphophallus titanum holds the record for the world's largest unbranched inflorescence, reaching up to 10 feet (3 m) in height. However, the largest individual flower belongs to Rafflesia arnoldii, also from Sumatra, which produces a single flat bloom up to 3 feet (1 m) across. These are two different botanical records: unbranched inflorescence versus single flower.
