What are Hardiness Zones, Gardening Zones, Growing Zones and Plant Zones?

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 and contain data from the period 1960-1990. This updated version of the map was created by Plantmaps and includes climatology data through December 2009. This map also uses a wider range of climate data than the current USDA map, which limits the zones to 30 years of data.
