Leucocasia gigantea (Blume) Schott. was named and described by Heinrich Wilhelm Schott in Oesterreichisches Botanisches Wochenblatt in 1857.  

Colocasia gigantea (Blume) Hook. f. is the correct and accepted scientific name for this species of Colocasia. It was first described as such by Joseph Dalton Hooker in The Flora of British India in 1893. It was first described as Caladium giganteum by Carl (Karl) Ludwig von Blume in Catalogus…. in 1823. Have no clue what the …. is supposed to mean.

I am not sure when, but recent testing confirmed that the Colocasia gigantea was more closely related to Alocasia than Colocasia. But, since there were other unique characteristics, it was reclassified as Leucocasia gigantea as it was named in 1857. Back in a genus all by itself. Maybe at some point, other species will be added to the genus.

I bought my first Colocasia gigantea from Wellspring Gardens in the spring of 2009. It was a very small starter plant, so it really didn’t reach any good size, but the leaves were definitely larger than the other Colocasia and Alocasia I had bought that year (with the exception of the Colocasia esculenta).

Although the Colocasia gigantea and Colocasia gigantea ‘Thailand Giant’ are the same species, their growth and habit are different. Brian Williams of Brian’s Botanicals gives a pretty accurate description of the difference between the two, so you can just read what he says HERE.

My Colocasia gigantea did not survive the winter but I did buy a Colocasia gigantea “Thailand Giant’ in 2012 and another one in 2017.
