I have a colocasia, pictured but have no idea what type it is. The leaves on this one are just over 3 feet wide but I have seen them around town with leaves between 4 - 5 feet wide.
Its not C. Gigantea thai giant, because we are not allowed to import them into Australia, but its very similar, I asked the local nursery and they said they didn't know because they've been crossed that many times. So here I am.
Hope someone can help Identify this.
Thanks

C.gigantea Thai giant. I wasn't sure if we had them in Australia, I hope your right.

Thanks

An image of the inflorescences which are unlike other Colocasia will confirm. Genetic studies show it to be in a separate genus from Colocasia, more closely related to Alocasia, so once a paper is published it will be Leucocasia gigantea.

Thanks for your helpful feed back, I am new to the world of colocasia and alocasia.
I don't know if you can tell anything by this photo I took.
Thanks again.

The shape and color of the inflorescences look right for C. gigantea. You can add this to the way that the leaf blades on your plant don't bend down where they meet the petiole.

The spathe limb/blade (the part of the spathe above the constriction) is slightly longer than the spathe tube (the part below the constriction). In other Colocasia the spathe limb is usually much longer, often several times the length of the tube.

Thanks again, learning a lot here. One more question.

Thanks

Sorry I remembered one more thing. a couple of other ones I have started flowering in September last year, which is the beginning of our spring and have flowered none stop since. We are now one week away from the start of our winter and they are still pushing out flowers. The weather is cooling down now, but the temp here is still nice, around 28 c or 82 F
Do you know if this is normal for them to flower this long.
Again thanks

I've been told this sort of continuous flowering "may be unusual". Sorry I couldn't help you with this. I don't know how many clones there are here in the U.S. but I've never seen anything like it in my garden.
