USDA Hardiness Zone 6b
Zone 6b on the 2023 USDA Plant Hardiness Zone Map means an average annual extreme minimum temperature of -5°F to 0°F, averaged over 1991 to 2020. The zone is about the coldest winter night, not frost dates or summer heat, so towns in the same zone can have different frost dates.
