There are clearly a few monster yams, likely Caribbean White, at the NW corner of my house that grew there when that area was consumed by Cherokee Rose and Pandorea Vine that I do NOT want to grow there again! I am digging them up today, will give one to Mary Jo who loves to eat them but has no room for the vines. These emerging vine tips make me think that the tubers could be quite big. Fried yams for lunch!
