Most plants will tolerate quite a broad range of pH. It is more common to find lists of the plants that absolutely require an acidic soil, say below 5.0, such as azaleas and rhododendrons. In your area -- and across the northeast, it would be very unusual to find native soil that is not somewhat acidic to possibly neutral if it has been limed repeatedly and recently it might be 7.0 or a bit higher. Truly alkaline soils, such as with a pH over 8, tend to occur in desert areas in the western part of the US. In any case, here is a listing showing optimal pH readings for a wide variety of plants. Please remember that most plants do grow in variety of pH readings between about 5.0 and 7.0, so this is simply the optimum.

I hope this helps.
