The best plants for zone 8 – expert advice on the vegetables, native perennials and flowers that will thrive

How cold is your yard in winter? How deep does the winter frost penetrate the ground? Will plants that are native in your area survive winter better than plants that grow wild in other parts of the world?

The answer to all these questions is that gardeners no longer need to ask them. It’s now easy to choose plants for your yard that will not be killed by winter’s cold; to choose plants that have exactly the winter tolerance you need. 

This is how it works. The United States Department of Agriculture (USDA) has divided the country into 13 different areas, hardiness zones, according to the average lowest winter temperature. The USDA accessed data from weather stations across the country to create the map, which was last updated in 2023. Here, we take a closer look at what this means, and the best plants - from bulbs, trees, natives, vegetables and annuals - to grow if you live in zone 8. 

US hardiness zones explained

Hardiness zone 8 covers areas with a lowest winter temperature of 10F to 20F. For additional accuracy, each zone can be split into two subzones, zone 8a (10F to 15F) and 8b (15Fto 20F), for example, but this level of detail is not always needed.

At the same time, for decades now, horticultural experts across the country have been assessing all the plants that we grow and allocating each variety a hardiness rating, that indicates the lowest winter temperatures that the plant will tolerate. 

Hardiness ratings for individual plants can be found on plant tags, on websites hosted for mail order nurseries and advisory organizations, in books, magazines – hardiness ratings are cited Z8 or Zone 8. These hardiness ratings match the hardiness zones so you can tell in an instant if a plant is hardy enough to survive the winter in your area

Choosing plants for Zone 8

Matching the USDA Hardiness Zone for your area with the hardness rating for individual plants is the best guide to which plants are winter hardy in your area.

But although this is by far the best approach to choosing plants, it’s not 100% guaranteed. Soil conditions, drainage, shelter and other factors are also an influence. So if you garden in zone 8 and you’re tempted by a plant rated as hardy in a zone 9 then give it a try – but be prepared that it could struggle.

Remember, too, that plants rated as hardy in a colder zone will almost always be hardy in zone 8. It will usually be easy to grow plants in zone 8 that are rated as hardy in zone 3, zone 4, zone 5, zone 6 and zone 7, although for some it may be too warm. In this case, you will sometimes see plant hardiness ratings cited as Z4-7, for example.

The USDA Hardiness Zone map was updated in 2023, to take into account how our climate has been changing as North American winters have become warmer. For many years I gardened in zone 5, but the latest revision of the USDA map, reveals that the garden is now assessed as zone 6. So look out for updates from the USDA.

Finally, plants in containers are a special case. A plant growing in the ground has soil all around the sides of its roots, and this works as insulation that reduces the amount of frost that penetrates. That same plant grown in a pot has no insulation around the sides of its roots so the cold penetrates farther and more easily and may well cause damage. The result is that plants for containers need to be rated one zone warmer than plants growing in the ground.
