About The USDA Idaho Hardiness Planting Zone

If you are looking to find out what your growing zones in Idaho are, you will need to look at a USDA map of the plant hardiness zones. The above map is for Idaho plant zones and can help you find what planting zone you live in. 

You can find your Idaho hardiness planting zone by looking at the map above and locating approximately where you live on that map. Note the color of the growing zone in Idaho where your town is located, and then compare that color to the legend to the right.

This Idaho plant zones map is based on the 2023 revision to the USDA planting zones. This change was made to the hardiness zone map due to the increasingly warm climate that has occurred over the past few decades.

The reason you should take time to understand your Idaho hardiness planting zone is because you should be choosing plants for your garden that will survive the winter in your area. By choosing plants that either match your zone or will survive in a lower zone, the plants you choose will be better equipped to survive the conditions in your area. If you choose to grow plants that are suitable for a higher zone, you will need to provide extra protection, or even bring these plants indoors for the winter.

You can find plants appropriate for growing zones in Idaho at your local nursery. Reputable nurseries will only sell perennials for landscaping that will survive the winter in your area. These plants will be clearly marked with the zone that they are meant for. Your local nursery may also sell some non-zone-appropriate perennials, but these will be marked as non-hardy.
