The source of this helpful USDA Plant Hardiness Zone Map post rely on images and information from Oregon State University OSU and USDA Agricultural Research Service (United States Department of Agriculture). If you know your area zone already you don't have to proceed down, instead, just click on your zone area on the table above to know what are the plants that can best and commonly grown by gardeners and farmers in your area.

What are the Hardiness Zones, how to figure out my hardiness zone and how do I find what best plants that suit my climate?

As per the USDA, the Plant Hardiness Zones Map divide the United States, Canada, UK, Europe and the remainder of the world into 13 areas based on a 10 degree Fahrenheit difference in the average annual minimum temperature. It is now considered the standard by which farmers, gardeners and growers can determine which plants, trees and perennials are most likely to thrive at a location. For example, if a fruit tree is considered hardy to zone 5-8. This means it can survive the extreme harsh weather of the hardy zone areas 5, 6, 7 and 8.
