When clearing out tubs yesterday, I discovered very large, heavy round ?tubers in 3 of them. The largest is almost spherical with a diameter of about 9 inches. I grew begonias in these pots last summer but these look much to big to be begonia corms. Can anyone help please

I think it is Begonia, the tuber full of water is large and spherical. Here is a link with pics to check. (http://www.wellsphere.com/gardening-article/planting-begonia-tubers/515411)

hard to say, no idea what you've been growing. If they're not potatoes, maybe Colocasia? Alocasia?
