Understanding Hardiness Zone for Planting Plants

Planting Flowers
Not every plant or flower can thrive in every climate. When choosing perennial plants to keep, it is important to choose varieties that can survive and thrive year-round in your area. The planting zone determines which plants can thrive in your area.

What people refer to most often are the hardiness zone maps produced by the US Department of Agriculture (USDA) and the Köppen Climate Classification (Köppen). Different sizes are used to map each country to clarify the area or make it easier to understand.

NOTE: Zone maps are not absolute. If you come across information that contradicts your own experience, you may be living in a microclimate. Soil, humidity, heat, wind, and other conditions also affect the survival of individual plants.


USDA MAP (Only for the United States)

USDA Hardiness Zone
The USDA Plant Hardiness Zones Map is based on average annual minimum winter temperatures. The map is divided into thirteen distinct 10 ºF zones, which are further divided into 5 °F sub-zones.



Köppen Climate Classification
The Köppen Climate Classification is complete and clear to classify which regions are included in the tropic climate, especially the climate on the equator.

Planting native species (native plants that grow naturally where you live) is a surefire way to achieve a stable garden. So naturally, they will develop well because they are in their habitat.
