This variety of Alocasia Macrorrhiza is sometimes
The Alocasia Macrorrhiza shown within this site can easily grow to a height well over 6 feet.
As the Alocasia leaves die off a dry brown husk will remain. If the husk were to be removed you would see a ring under the husk. This ring is a scar from the Alocasia leaf that was there. The rings are a good indicator of how many leaves the Alocasia Macrorrhiza plant produced.
When actively growing, the Alocasia stalk grows larger with each new leaf. Under tropical growing conditions, the Alocasia stalk will grow to about 4 inches in diameter or more. The Alocasia stalk can reach heights of about 6 feet or more in warmer tropical climates. In less than best conditions the Alocasia stalk might grow like vines along the ground producing plantlets from the stalk at varying intervals. If the Alocasia plant does not have the best growing conditions, water, temperature, and light, it will begin to go dormant indicated by each new leaf getting progressively smaller. The plant will eventually slow down until it receives the proper care. If the proper conditions are restored, the plant will revive from the smallest of remaining piece of the tuber that can be found. When the plant is returned to an environment with the proper growing conditions, it will again start to come alive with new growth.
Review the "Book of Records" page and see if yours are larger than the recorded sizes.
Some Alocasia have been described as "black". The Plumbae variety shown within this site have a dark purple color. Dark enough to call black. While this variety is new to me, I have been told that the Plumbae variety will get as large as the Macrorrhiza.
Plumbae or Plumbea? I am not sure of the correct spelling, I believe Plumbae is correct.
Plumbea is listed within this site for search key words where spelling of Plumbea might occur that way. Please forgive me.
