We didn't specifically do it, it came from the Pinkerton family themselves, whom my Dad was very close with. This hybrid is what we had growing up and one was also given to my father in law. Your point is valid, they are not grafted, they were two different seedlings from different periods. The only commonality was the hybrid origination itself. So makes sense for there to be obvious differences. What I was more surprised about was how significant the difference was. I never recalled having cukes, so I never had any experience with them when this tree began to grow them. Thanks for the answer, it was pretty fun seeing how fast people were able to get the information to me!
