Well I see you all might want a ID on it. Many of you are right it is Xanthosoma Sagittifolium a common weed in florida. I grow them myself they are great plants if we have a hot summer and plenty of water they can get to a monsterous size. Now to help you guys ID your plants. Colocasias will have a heart shaped leaf usually the thing is the back lobes will be fused and Xanthosomas will not. So when you look at a leaf and see were the stem meets the leaf if you are able to see the stem through the cut in the leaf its a xanthosoma and if not its more likely a colocasia. Now their are other species that can mess this up specially Alocasias but for the most part this should help out also Xanthosomas will have white sap.

Here is a picture of Xanth Sagittifolium mature.
