USDA Hardiness Zone 3 is one of the coldest plant hardiness zones in the United States. It covers regions where the average annual extreme minimum temperature ranges from -40°F to -30°F (-40°C to -34.4°C). This means that plants suitable for this zone must be able to withstand extremely cold temperatures.
