USDA hardiness zone is a geographical categorization of area in which a specific type of plants are capable of growing, defined by many climatic conditions, including its ability to withstand the minimum temperatures of the zone. For example, a plant that is described as “hardy to zone 11” means that the plant can withstand a minimum temperature of +4 °C. Hardiness zones are developed by the United States Department of Agriculture (USDA), use of the zones has been adopted by the other countries.
