The USDA Plant Hardiness Zones have changed. The new map takes into consideration climate change, elevation, large lake effects, and a few other things. Details and an interactive map are available on the USDA Plant Hardiness Zone Map page. Hunt county is now shown as firmly 8a, with temperatures to 10 to 15 degrees F as lows in the winter. This data reflects temperatures from 1976 to 2005. Although heat and a lack of water are more a limiting factor in our area, keeping the new zone in mind while ordering plants to replace those lost from the drought would be a good idea. For more information, see my article on understanding the USDA zone map.
