Planning a Native Plant Paradise: A Guide for East Tennessee Gardens

East Tennessee, with its diverse landscapes and vibrant seasons, provides a rich canvas for native plant gardening. The region’s climate, characterized by warm summers and distinct seasons, allows for a stunning array of flora to thrive. Whether you’re a seasoned gardener or just starting, incorporating native plants into your landscape offers numerous benefits, from enhancing local biodiversity to creating a resilient, beautiful garden.

This guide will help you navigate the exciting journey of establishing a thriving native plant garden, focusing on key considerations and plant selections tailored for East Tennessee.

Understanding Your Site

The foundation of any successful garden begins with a thorough understanding of your site’s conditions. This includes assessing sunlight exposure, soil type, and existing features. The following aspects are important to analyze before you start your garden:

• Sunlight: The amount of sunlight your garden receives is a crucial factor in plant selection. Areas with full sun, meaning at least six hours of direct sunlight per day, will support a different range of plants compared to partially shaded spots. Note the duration and intensity of sunlight throughout the day and across the seasons.
• Soil: Soil composition significantly influences plant health. Conduct a soil test to determine its pH, nutrient levels, and texture. Native plants are often well-adapted to local soil conditions, but understanding your soil will help you amend it if necessary or choose plants that match your soil type.
• Microclimates: Within your garden, microclimates can vary due to structures, slopes, or other features. These variations can create pockets of shade, areas of increased heat, or variations in moisture. Observe these subtle differences as you plan your garden layout.

Planning for Success

With an understanding of your site, you can begin to plan the layout and plant selection process. Here’s a breakdown of essential considerations:

• Design and Layout: Consider the overall aesthetic you want to achieve. A well-designed garden often includes a mix of plant heights, textures, and bloom times. Group plants with similar needs together, and create pathways or focal points to enhance the garden’s appeal.
• Irrigation: Especially during the establishment phase, a reliable water source is essential. Consider installing a DIY irrigation system or other watering methods to ensure your plants receive adequate moisture, particularly during dry spells. Native plants are often more drought-tolerant once established, but consistent watering in the first year or two can significantly improve their success.
• Plant Selection: Choose native plants that are well-suited to your specific conditions. Research plants that thrive in full sun, partial shade, or varying soil types. Consider the mature size of each plant to ensure they have adequate space to grow. Selecting plants that offer diverse bloom times will extend the visual interest throughout the growing season.
• Resources and Support: Take advantage of local resources and support networks. Your local extension office can provide valuable advice on plant selection, soil testing, and gardening techniques specific to your area. Additionally, local nurseries specializing in native plants can offer expert guidance and high-quality plants.

Plant Recommendations for East Tennessee

East Tennessee’s climate allows for an exciting range of plants to thrive. Here are some examples of plants that are well-suited for the region:

Shrubs

• Carolina Allspice (Calycanthus floridus): A fragrant shrub with unique maroon flowers. It tolerates a range of conditions and provides visual interest throughout the growing season.
• Ninebark (Physocarpus opulifolius): Offers attractive foliage and clusters of white or pinkish flowers. Its exfoliating bark adds winter interest.
• Spicebush (Lindera benzoin): A host plant for the Spicebush Swallowtail butterfly, this shrub features fragrant yellow flowers in early spring.

Perennials

• Purple Coneflower (Echinacea purpurea): A classic native perennial with daisy-like purple flowers. It attracts pollinators and is relatively drought-tolerant.
• Black-Eyed Susan (Rudbeckia hirta): Known for its cheerful yellow flowers with dark centers, this plant thrives in full sun and is easy to grow.
• Butterfly Milkweed (Asclepias tuberosa): A crucial host plant for monarch butterflies, featuring vibrant orange flowers.
• Wild Senna (Senna marilandica): Adds elegance to any garden with its beautiful yellow flowers and interesting seed pods. It attracts butterflies and other pollinators.
• Bee Balm (Monarda species): Attracts pollinators with its vibrant, showy flowers, and adds a splash of color to the garden. It prefers full sun to partial shade.
• Asters (Symphyotrichum species): Provides late-season color with its daisy-like flowers in various shades of purple, pink, and white. They are essential for late-season pollinators.

Trees

• Eastern Redbud (Cercis canadensis): Features beautiful pink flowers in early spring, followed by heart-shaped leaves.
• Serviceberry (Amelanchier species): Offers year-round interest with spring flowers, edible berries, and colorful fall foliage.
• River Birch (Betula nigra): Adds visual interest with its peeling bark and provides shade with its graceful form.

Site-Specific Considerations

The following site-specific information will help you make appropriate plant selections.

• Full Sun Areas: For areas that receive full sun, consider plants like purple coneflower, black-eyed Susan, butterfly milkweed, and bee balm. These plants thrive in direct sunlight and offer beautiful blooms throughout the season.
• Partially Shaded Areas: In areas that receive partial shade, you can plant shrubs like Carolina allspice and spicebush. Wild senna can also do well in these conditions.
• Hell Strip: If you are dealing with a hell strip, which typically receives full sun and may have challenging soil, consider tough and adaptable plants. Black-eyed Susans, coneflowers, and drought-tolerant grasses can be excellent choices for these areas. An irrigation system will be crucial.
• Shaded Areas: In the areas between garage and fence, you’ll want to pick shade-loving plants like ferns, woodland wildflowers and certain shrubs. The specific choices depend on the degree of shade and soil conditions, but options like native azaleas or dogwoods can thrive in these spots, adding beauty and structure to your garden.

Implementation and Maintenance

Once you have your plan and plants selected, it’s time to start implementing your garden.

1. Prepare the Soil: Before planting, prepare the soil by removing weeds, rocks, and any debris. Amend the soil as needed based on your soil test results. This may involve adding compost, organic matter, or other amendments to improve drainage and fertility. Make sure to have a basic understanding of what different plants prefer.
2. Planting: When planting, follow the spacing recommendations for each plant and water them thoroughly after planting. Mulch around the plants to retain moisture, suppress weeds, and regulate soil temperature.
3. Irrigation: Set up your irrigation system to provide consistent watering, especially during the establishment phase. Monitor soil moisture levels and adjust your watering schedule as needed. Some plants will require more water than others, especially during their first year.
4. Maintenance: Native plant gardens often require less maintenance compared to traditional gardens, but some care is still needed. Weed regularly, especially in the first year. Prune shrubs as needed to maintain their shape and encourage new growth. Deadhead spent flowers to encourage continued blooming. Mulch to keep soil moist and cool.
5. Observation: Observe your garden regularly. Notice how plants are growing, what is thriving, and what may need adjustment. Monitor for any signs of pests or diseases and take appropriate action. Make notes throughout the growing season, and take pictures to track changes.

Seeking Support and Resources

Don’t hesitate to seek out additional resources and support. The local extension office is a great starting point. Tennessee’s Tree Day can provide additional information to promote the growth of trees. Many local nurseries specialize in native plants, offering expertise and high-quality plants. Online resources, such as native plant societies, can also be valuable.
