What is the maximum harvest that can be expected from one TPS plant?  I don’t have a final answer for that question but clearly these two Diamond Toro TPS harvests are raising the bar.  This is yet another Tom Wagner TPS variety.  I really admire all of the work that he has done with potato breeding and highly recommend buying some seeds from him in addition to growing TPS that you can harvest from commonly available potato varieties like Yukon Gold.  These plants grew huge and set multiple tubers per stolon, some of which extended over two feet away from the base of the plant.
