Fall 2016, I planted around 40 paw paw seeds and 50 persimmon tree seeds. Most came up last year. I potted them up and gave a bunch away. Looking at them the other day ( I was planning on planting them). I found every last one of them dead. We had awful winter. Shockingly, the small kiwi vines I in the same spot, in the same pots are all alive. My conclusion is that cold hardy kiwi are more hardy than trees native to My area!
