Learn about titan arum seed germination, flowering time, and the unusual characteristics of this tropical plant.
Sow fresh, viable seeds in a warm, moisture-retentive but well-draining growing medium. Maintain temperatures around 24–30°C (75–86°F), provide high humidity and bright filtered light, and avoid waterlogging. Follow the seed supplier's instructions for sowing depth and care.
Titan arum can take many years to flower from seed, often a decade or longer under cultivation. Flowering depends on the plant's development, stored energy, growing conditions, and dormancy cycle, so an exact flowering date cannot be guaranteed.
It is called the corpse flower because its large flowering structure produces a strong odor resembling decaying flesh when it blooms. This scent helps attract carrion-associated pollinators, including certain beetles and flies.
