Alocasia portei Schott is the correct and accepted scientific name for this species of Alocasia. It was first described by Heinrich Wilhelm Schott in Bonplandia (Corrientes) in 1862.
I bought my Alocasia portei from Wellspring as a started plant in the spring of 2009. It did very well through the summer but went dormant over the winter after I put it in a pot and brought it inside. Then the bulb rotted.
Websites say that Alocasia portei can grow to a height of 8-9 feet tall. It is cold hardy in USDA Zones 9-11 (20-40 degrees F). It has lobed leaves and marbled petioles.
There are two varieties of Alocasia portei is being marketed under the name of ‘Malaysian Monster’ and ‘Megalodon’™. There are probably others as well.
To bad mine died before it reached any size. Maybe one day I will try it again. If you have any comments, questions or suggestions about Alocasia portei, I would love to hear from you.
There isn’t much information about this species online. Even Plants of the World Online doesn’t have it listed as a species…
