Zones are determined by the United States Department of Agriculture (USDA) to give guidance to the lowest temperatures at which a plant will survive. Various factors weigh in to determine which plants will fit in a given zone, such as temperature, rain, elevation, snow, humidity, winds, and the amount of sunlight. The USDA has created a Plant Hardiness Zone Map. It shows people how a certain plant or shrub will grow in a particular area. There are eleven separate zones – each indicating the coldest temperatures at which a plant will thrive. Zone 1, for example, is for areas that have average yearly minimum temperatures that are lower than -50 degrees Fahrenheit (-45.5 degrees Celsius).
