These plants are ½” - ¾” tubers in 4" plastic pots. With proper culture I expect these will flower in 1 - 2 years. These plants were puchased as bare root tubers in 2019 as Am. kachinensis. However the petiole patern and leaf structure are quite different from that of my other Am. kachinensis. It has been suggested to me that this is Am. yunnanensis.
Several small tubers were purchased in 2019. These have not flowered yet. It is hoped that the first will flower in 2021. This is why I have the (?) in the name. The plant is quite different from a known Am. kachinensis in my collection. Am. yunnanensis has been suggested as a possible identification. It is PROBABLE this is misidentified, but regardless this is not one of the common species.
This species is native to Yunnan Province China, northern Laos, and Northern Vietnam. This species as with most Amorphophallus and Arisaema species are seasonally dormant. Plants of this species grow 20” – 30” tall. Each tuber produces a single stem that terminates with a single “leaf” or inflorescence. Each leaf consists of a large umbrella of smaller leaflets that is 18” - 24” across. The leaf stem of this strain is medium green-gray with elongated oval shaped white spots. The plant alone is very ornamental. The inflorescence is produced from the naked corm before the leaves are produced. The inflorescence is 10” – 20” tall. The inflorescence is single flowered. The “flower” is actually a modified inflorescence that consists of the spathe (outer ornamental part) and the spadix (internal sexual bits). The spadix is 3” – 7” tall. The spadix appendage (apical non-sexual part) is white to off white, bulbous corrugated (wrinkled), and vaguely tapers to a blunt point. The spathe that surrounds the spadix is about 5” – 10” long. The spathe is light green with a dark pink-purple to purple base inside. The exterior is darker green with a darker purple base. If pollinated, the Infructescence produces green berries that turn orange when mature. It is important to wear gloves if you harvest the berries as they juice can stain and irritate mammalian skin.
