Be sure to read how we assign hardiness zones to our plants.
The USDA Plant Hardiness Zone Map is based on the average annual minimum winter temperature, divided into 10-degree F zones. Each zone is then subdivided into 5-degree F sub-zones. Zone numbers increase as you move from north to south.
Zone 6a annual minimum winter temperatures should be -10 to -5 °F (-23.3 to -20.6 °C). Zone 6b annual minimum temperatures should be -5 to 0 °F (-20.6 to -17.8 °C). Keep in mind that the zone designation does not tell you how many days the area may reach those average minimums. There can also be a major difference between what plants will grow in the 'a' or 'b' sub-zones.
