To account for the differences between the climates of the Southeast and West, we have split the "warm" end of our hardiness ratings. In the example Hardiness Zone: 4-7 S / 4-9 W, the first number of each range (4) indicates cold hardiness. The second numbers (7 and 9) indicate the limits of a plant's range in the Southeast (S) and West (W).
