Pennsylvania zones include 5a, 5b, 6a, 6b, 7a and a very small section of 7b. If you have a difficult time finding your location on the above map, you can visit the USDA site where you can input your zip code to find out exactly which zone you are in.
The current USDA zone map has much of Northern Virginia in zone 6b, with a blob Loudoun County in zone 7a. I think my house is in that 7a blob, but I am not sure. There was an updated version of the map released in draft version that got rid of the 'a' and 'b' designations.
