USDA HARDINESS ZONE MAP
The 2012 USDA Plant Hardiness Zone Map is the standard by which
gardeners and growers can determine which plants are most likely to
thrive at a location. The map is based on the average annual minimum
winter temperature, divided into 10-degree F zones.

Suggested hardiness zones are included for each item in
this catalog. For example, a plant’s range listed at 4–9 means the plant
is known to be hardy in zones 4, 5, 6, 7, 8, and 9.
Keep in mind
that local variations such as moisture, soil, winds, and other
conditions might affect the viability of individual plants. Urban areas
and regions with bodies of water or mountains may contain climatic
pockets that mirror warmer or cooler zones than the surrounding region.
If it looks on the map like you should be in a different hardiness zone
than the one we provide for you, you’re likely in a microclimate too
small to represent on the map.
