My neighbor gave me three plants this past spring, Sun Choke, I think is what he called them. I dug under one of them to see what I could find. I found a bunch of white, hard knots. Do they always look like this, and what do I do with them? They were planted beside the driveway in hard, sorry soil and had very little care. Is this a plant that is worth growing? I assume that if it were planted in better soil the fruit would be larger and smoother?
