The famous corpse flower is renown for having the tallest inflorescence in the world. It blooms over a few days and produces a stench like carrion in order to attract its pollinators.
Amorphophallus decus-silvae is known to be even more colorful and showy than the gigantic titanum. It's no slouch in the size department either with some inflorescences recorded at 10' tall. We find this species to be an easy grower. We grow it in a mix of equal parts peat, perlite/pumice and orchid bark and use 1/2 strength osmocote plus applied in the soil every 6 months. We make sure it's always above 60 degrees with high humidity. They die down to their corms periodically and will rest for a few months before putting out new stems. Given appropriate conditions, they will produce huge corms weighing over 100 pounds and will bloom in 5-10 years.
