That's understandable. I was just figuring that PA is about as far north as IL, so I thought they would be approx the same zone. I didn't really think about the effects of the mountains, or the ocean. Truthfully, I didn't realize that the Atlantic even touched PA. I guess I need to brush up on my geography!!
If you're that much warmer, that could be why the Reiter's do well by you. I was told I was pushing the zone with them here, and they did better in warmer climes.
