There is, or at least used to be, a good deal of tobacco grown in southeastern PA. I can remember driving out the PA turnpike and seeing miles and miles of tobacco fields. A hundred years ago, there were a lot of cigar manufacturers in PA. Like breweries, it was a more local industry so they were found in many states. Middleton still manufactures in PA.
We always think of tobacco as being a crop in the south, but PA has a fair bit, as do other states. And, as mentioned by mso489, a lot of cigar wrapper tobacco was (maybe still is?) grown along the Connecticut Rive in CT. Now, when you see that a cigar has a Connecticut wrapper, very often it is the same variety grown under similar conditions elsewhere. The 1961 movie, Parrish, is set on a tobacco plantation in the Connecticut River valley.
