Thailand Giant Elephant Ear

Colocasia Gigantea is a beautiful elephant ear that can reach enormous sizes if given the right conditions. It loves water, so be sure to give it plenty. You can even grow it in standing water (pot or not).

This plant will produce seed pods pretty regularly as it grows large enough. Gigantea can commonly self pollinate, though it seems to not breed with others such as Fallax and Affinis.

Once mature, beneath the spath (bloom), you should see the pod. Many will have 5 or so spath flowers, each with a pod beneath it, all from a single leaf node. It will likely take several weeks for the pod to ripen and burst - but when it breaks open, it's ready.
