The Sunset Gardening Books are often considered to be the bibles for gardening and plant information. These books however use their own plant hardiness scale, but along with detailed zone maps - some very specific to certain areas - they mention the pros and cons for each zone, which plants do well, and which ones don't.
Microclimates also play a big role in choosing the right plant for the right area. For example, there's a large difference between where I live and where people live just a few miles to the north... though the USDA zone will show us as being in the same zone. Consider your microclimate to be your "fine tuning".
