Vine Peaches

I received a packet of these seeds as a gift with my purchase of some ranunculus and lilly bulbs and am going to get them in the ground tomorrow (I just widened my garden by 2 feet on either side) and was just wondering if anyone had tried to grow these before? I read online that they are rare nowadays but used to grow wild in the US. I might be starting too late with them but I want to give some a try. I might refridgerate the rest and try to save them for next spring.
