One member of this genus, Amorphophallus titanum, produces the largest inflorescence in the plant kingdom that tops out at over 8' tall. We occasionally sell this monstrous plant, but we find that our customers prefer the more cold hardy species such as the konjac plant. Amorphophallus flowers are famous for their malodorous nature, which attracts flies and repels people with sensitive noses. But they sure are pretty! The smell is produced in waves via a fascinating mechanism. The odoriferous compunds are volatile chemicals that evaporate easily when heated. Amorphophallus plants have the ability to increase respiration to a very high level for a couple of hours at a time. This increased respiration generates heat (almost 100 degrees F) which in turn volatilizes the odor causing compounds inside the flower and produces a wave of stinkiness. This process is called thermogenesis. Thermogenesis is rare in plants and is poorly understood, but chemically, the process is not too dissimilar from the heat generation process in mammals. Cool!
