Plant Hardiness Zones

Nine zones indicate the areas where various trees, shrubs and flowers are most likely to survive. These zones are calculated based on average climatic conditions and altitude of each area. The harshest zone is 0 and the mildest is 8. Each major zone is divided into subzones a and b (for example 3a and 3b) where zone a is slightly harsher than zone b.
