The U.S. Department of Agriculture has divided the United States and southern Canada into 11 zones for plant hardiness, which indicates what plants can survive the winter in a given area. Tennessee is in zones six and seven.
Considerations
Each hardiness zone represents a 10-degree difference in average minimum temperature. Zones two through 10 are subdivided into two groups each, so you have a zone six A and B, for instance. Cold tolerance is vital to plant survival, so it is best to err on the side of caution.
Features
Tennessee is a long state, stretching nearly 500 miles east to west, but is not very deep, at less than 200 miles north to south. The state is also on the edge of zones six and seven, so there is a lot of variety in the hardiness zones.
Geography
Much of Tennessee is in zone six, which means the average low temperature is 10 below zero degrees Fahrenheit to zero degrees. The bottom part of the state is in zone seven, which means an minimum average temperature of zero degrees Fahrenheit to 10 above.
