Hardiness Zones, Gardening Zones, Growing Zones and Plant Zones refer to defined geographic regions that can support specific plants, flowers and trees. The zones define a minimum range of temperatures that a plant or tree can survive safely in that zone. The most commonly used Hardiness Zones were defined by the USDA. This map applies the USDA hardiness zone classifications to zones in Canada derived from historical climate records available from the National Climate Data Archive.
