Plant growing zones provide insights about what can grow where.
Plant hardiness maps allow producers to label their plants as being suitable for particular areas, as a result, growers can confidently buy plants that will survive and thrive in their locality. The zones apply to plants growing outdoors with no protection throughout the year, provided with adequate water.
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, however other variable factors are relevant to the survival and growth of many plants; frost dates, frequency of snow cover, duration of cold temperatures for vernalization, summer temperatures, sun intensity insolation, length of hot weather, micro climates, atmospheric wind currents, ENSO variations, reliability of snow cover, day length, humidity, precipitation, storms, rainy and dry cycles, coastal or inland location, elevation above sea level, soil type, soil drainage and water retention, water table, tilt towards or away from the sun, natural or manmade protection from excessive sun, snow, frost and wind, amongst others.
For uniformity, USDA hardiness zones are stated for temperature sensitive plants in accordance with their climatic tolerance, unless specifically annotated. The following are zone maps of different parts of the world for ease of comparison so you can easily locate your growing zone, determine plant suitabilities for export, yield potential of different cultivars for commercial food growers and especially for regions of the world with very cold winters, when to plant.
