Alocasia Macrorrhiza
Originating in Southern Asia and growing throughout the
Southern Pacific. Ancient Polynesians (Hawaiians)
call the Alocasia Macrorrhiza plant `Ape. By some, this plant is referred
to as "wild" Taro.
This variety of Alocasia Macrorrhiza is sometimes referred to as
elephant ears or upright elephant ears. Upright is
used as a description of the Alocasia Macrorrhiza leaves standing straight
up pointing skyward. The descriptive comparison to
an Elephant's ear probably came from another plant
(perhaps Taro, Colocasia esculenta) with
leaves that do not stand upright, but rather point
towards the ground looking like the droopy ears of
an Elephant. All together, the description was applied
to the Alocasia Macrorrhiza describing them as
"UPright Elephant Ears", I have shortened it all and
refer to them from time to time as "UPees".
The Alocasia Macrorrhiza shown within this site can easily grow to a height well over 6 feet. The leaves of Alocasia Macrorrhiza push out of the center of the plant from within the innermost Alocasia leaf stem. After the leaves unroll and open the tips of the Alocasia leaves can reach heights of 10 and 12 feet! The Alocasia leaves are very impressive with widths about 2 feet and lengths reaching 4 feet. In some cases even larger.
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.
Alocasia Plumbae
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.
Gerry Herron from Kelowna, British Columbia, had this to say about this site.
"Your web site is by far the best, most informative, and interesting site of all the sites I have attempted to use. Yours is very user friendly."
Thank You Gerry.
This Alocasia information site has been designed for the hobby grower. Everyone is invited to explore the pages within this site and hopefully find it full of information on how to grow Alocasia. Please report any problems or bad information.
