Be sure to read how we assign hardiness zones to our plants.
The current USDA Plant Hardiness Zone Map was last updated in 2012 and 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 9a annual minimum winter temperatures should be 20 to 25 °F (-6.7 to -3.9 °C). Zone 9b annual minimum temperatures should be 25 to 30 °F (-3.9 to -1.1 °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.
