Nashville Planting Zone: What You Need to Know
Nashville, Tennessee, resides primarily in USDA plant hardiness zone 7a and 7b. This means the average minimum winter temperature in Nashville ranges from 5°F to 15°F, which is critical information for gardeners deciding which plants will thrive in their gardens.
Understanding USDA Plant Hardiness Zones
The USDA (United States Department of Agriculture) plant hardiness zone map divides North America into zones based on average annual minimum winter temperatures. These zones help gardeners and landscapers determine which plants are most likely to survive the winter in a given location. Nashville’s location straddling zones 7a and 7b indicates the range of temperatures plants will likely experience during the coldest months of the year.
Nashville’s Zone: 7a and 7b
Most of Nashville is in zone 7a. However, some surrounding areas, particularly those at slightly lower elevations, may fall into zone 7b. Zone 7a has an average minimum winter temperature of 0°F to 5°F, while zone 7b experiences average minimum winter temperatures of 5°F to 10°F. This slight difference can influence plant choices, especially for marginally hardy species.
Choosing Plants for Nashville
When selecting plants for your Nashville garden, it’s crucial to choose varieties rated for zone 7 or lower to ensure winter survival. Many plants labeled as hardy to zone 8 might struggle in Nashville’s colder winters, especially during unusually cold snaps. Some popular plants that do well in Nashville include:
- Coneflowers
- Black-Eyed Susans
- Hostas
- Daylilies
- Hydrangeas (certain varieties)
- Azaleas
Always check plant tags or seed packets for hardiness zone information before purchasing.
Microclimates in Nashville
Even within the same hardiness zone, microclimates can influence plant survival. Microclimates are small areas that have different environmental conditions than the surrounding area. These can be created by factors such as building walls, which can provide shelter from wind, or south-facing slopes, which receive more sunlight and heat. Understanding the microclimates in your yard can help you choose the best locations for your plants.

Local nurseries and garden centers can provide expert advice tailored to the specific conditions in Nashville.
