over ten years I have been growing an Amorphophallus
paeoniifolius that originally belonged to Bob deLaney of Apopka,
Florida. This particular clone can grow to a height of over two meters
with a canopy spread of over three meters. The petiole base at the surface
of the soil can reach 30 centimeters in diameter. During the 2000 growing
season, the tuber grew to a weight of 29 kilograms.
Old A. paeoniifolius such as this specimen, typically grow in a cycle of vegetation in the first season followed by winter dormancy as a large depressed-globose tuber. In the following growing season, the tuber produces the inflorescence, which quickly withers unless pollinated. After the passing of the inflorescence, the tuber remains dormant until the next growing season when a leaf sprouts to produce a new tuber.
