My son knows that I have always loved Elephant ears and he gave to me what he thought was a mammoth elephant ear tuber (he did this for mother's day). I planted it, late June, expecting an elephant ear, but a long stem vine, grew out with one leaf. Over the next few days, the leaf grew to about 4 inches across and the vine continued to grow, along with new vines and leaves. I have given it a trellis to grow on and it is really growing fast, but so far it only has the beautiful wide leaves that are heart shaped. I would love to know what this is, as I have a 8'wide pergola that I might wish to move this to.

Thanks,
