What to plant in zone 7: uncover the trees, shrubs, flowers and crops that will thrive in this climate zone
Plants vary in their ability to survive the winter. A few will endure the coldest temperatures that our country has to offer, while the plants that thrive in the warmth of a tropical Florida will grow less well in cooler regions and will often be killed in winter in cold areas. It’s all a matter of right plant, right place.
As we look at the continue with our series on what to plant in the 13 different US hardiness zones and move into warmer climates, the range of plants that can be grown expands. The last frost date is earlier, the first frost date is later, and with a longer growing season a wider range of plants can enjoy the time and the conditions that will allow them to mature reliably.
You can find all the information about the average temperatures and location of US hardiness zone 7 here. In this feature, we take an in-depth look at a vast range of plants, shrubs and crops that will thrive in this part of the US.

Choosing plants for Zone 7
The first thing to remember is that if a plant is rated at zone 7, it will also be hardy in warmer zones – Z8 and up. For some plants, there comes a point where the winter (or sometimes the summer) is too warm so some plants are rated, for example, Z4-8. It’s also worth keeping in mind that, if you’re tempted by a plant rated has hardy in zone 8, it may thrive in your yard in a sheltered site and with good drainage. A potential favorite is always worth a try.
Also, the North American climate is changing – winters are becoming warmer. For many years I gardened in zone 5, but the latest revision of the USDA map, published in 2023, reveals that the garden is now assessed as zone 6.
Finally, a special rule applies to plants growing in containers of all kinds. Frost always penetrates the soil in containers more than it penetrates the soil in the yard as the roots of plants in containers are surrounded by icy air. So, for planters, always choose varieties rated one zone warmer than the zone for the garden as a whole.
