10 Shrubs That Thrive in Tennessee's Climate Year-Round

Tennessee gardens also gain one of the most useful landscape investments by planting shrubs since they bring structure, seasonal color, and provide wildlife habitats. The USDA Zones 6b-7b are in a humid summer, mild winter, and diversified soil that many year-round shrubs are adapted to. Adaptable and native ones also have fewer maintenance needs after establishment. Several hedges, foundation plantings, borders, and wildlife gardens also contain shrubs, which are an ideal way to go due to both longevity and beauty. Our years of experience in providing Tennessee landscapes have shown what types of year-round shrubs reliably perform in the state of Tennessee's soils, which are clay-loam in nature.

Climate Conditions That Shrubs Must Tolerate in Tennessee

The climate in Tennessee is associated with certain obstacles that planting shrubs should overcome to be successful over the long run. Temperatures in the summer are often above 90°F, with humid weather, which provides favorable conditions for fungal diseases on the vulnerable species. The low-maintenance shrubs have natural adaptation to these conditions in the form of resistance to diseases and heat sensitivity.

There are key climatic conditions, such as the following:

• Tolerance of heat and humidity: It grows well in hot and sticky summers up to 90°F.
• Cold hardiness: Can withstand winter temperatures of 0-10°F in Zones 6b-7b, occasionally.
• Soil adaptability: Adaptability to heavy clay soils with good drainage in Tennessee.
• Rainfall patterns: Management of 50-55 inches of rainfall, which occurs over seasons.

Tree Nursery Co. has been providing Tennessee landscapes with planted shrubs for decades. We have seen that species that are adapted to the local conditions need little interference.

Summer droughts are tolerated by most native species when the roots have grown.

Adhere to these practices that have been proven:
