Re: Elephant ear

All the commonly available Elephant Ears here are Colocasia esculenta. I
have seen it flower but don’t have a picture of it. Like Brian said it can
get really big here in the south. I have never seen Xanthosoma offered as
Elephant Ear here but have seen it in the grocery store as Malangua
(spelling?). I have 2 I have had for years that I got from the grocery
store. I'm not sure what the species is.

 Steve I find that just about all plants labeled commercially as Elephant
ear are Colocasias esculenta. The Xanthosomas are a bit harder to find and I
have rarely seen them commercially available. Yet many times I have seen
photos of Xanthosomas being used to sell Colocasias as well as Alocasias.
Caladiums are usually marked a bit better.  The colocasia in question though
is very interesting. It maybe a tetraploid possibly a triploid as it grows
much larger and very rarely produces flowers. I have only seen flowers one
time. The tubers can get extremely large 1 foot long or more and 6 to 8
inches across. I have seen a few photos of the plant grown to 10 feet tall
or more. I am not sure if this form is used in any taro production, it would
be interesting to find more on it's origins.  I have some good photos of on
around 8 feet tall or so.
