Coastal Virginia’s climate is one of the most distinct in the United States. This region is a beautiful blend of humid subtropical and temperate zones, influenced by the Atlantic Ocean and the Chesapeake Bay. The mild winters and hot, humid summers, coupled with frequent storms, salt exposure, and sandy soils, create a unique challenge for landscaping. But these conditions also present an opportunity to design a stunning, sustainable garden that thrives in harmony with the natural environment.
When planning a landscape for our region, it’s crucial to understand the challenges that coastal climates pose and to select plants and design elements that will withstand the elements. With thoughtful planning, you can create a resilient and beautiful landscape that captures the essence of coastal Virginia while minimizing maintenance needs.
1. Embrace Native Plants
One of the most important elements of designing a successful landscape for coastal Virginia is embracing native and adapted plants. These plants are naturally adapted to the local climate and soils, which means they are better equipped to handle the high humidity, salt exposure, and occasional flooding. Additionally, native and adapted plants often require less water and are more resistant to pests and diseases, making them a more sustainable choice.
Here are some great alternatives to traditional garden plants that are well-suited for coastal Virginia:
- Wax Myrtle (Myrica cerifera): A popular choice for coastal gardens, Wax Myrtle is an evergreen shrub that tolerates salt, sandy soils, and coastal winds. It’s also aromatic, with leaves that release a pleasant fragrance when crushed. Wax Myrtle can grow as a dense hedge or screen, providing year-round privacy and shelter for wildlife.
- Eastern Red Cedar (Juniperus virginiana): This evergreen tree is incredibly resilient to the coastal environment. It thrives in sandy soils, tolerates salt spray, and is wind-resistant. Eastern Red Cedar provides year-round coverage, with its dense foliage and blue-gray berries attracting birds and other wildlife.
- Sweetbay Magnolia (Magnolia virginiana): For a smaller, salt-tolerant alternative to the traditional Southern Magnolia, Sweetbay Magnolia is an excellent choice. This native tree features beautiful white flowers in late spring and summer, fragrant leaves, and a more compact form that fits well into smaller gardens. It can grow in a range of soil types, including wet, coastal areas.
- Inkberry Holly (Ilex glabra): If you’re seeking a holly that thrives in the coastal conditions of Virginia, Inkberry Holly is an excellent choice. Unlike traditional holly varieties, Inkberry grows well in both acidic and alkaline soils and can handle the salt exposure typical of coastal regions. Its dark green foliage provides a striking contrast in garden designs, and its black berries offer food for wildlife.
- Little Bluestem (Schizachyrium scoparium): Ornamental grasses such as Little Bluestem are ideal for coastal Virginia. This native grass has a striking blue-green color in the spring and summer, turning to a reddish-orange hue in the fall. Little Bluestem is drought-tolerant and thrives in sandy, dry soils, making it perfect for coastal gardens with limited moisture.
- Russian Sage (Perovskia atriplicifolia): An excellent choice for adding color and vertical interest, Russian Sageproduces tall spikes of lavender-blue flowers that are highly attractive to pollinators. This hardy perennial is well-suited for coastal gardens, as it thrives in full sun, well-drained soils, and dry conditions. Russian Sage can tolerate salt exposure and dry spells, making it a fantastic addition to the landscape.
These native/adapted plants not only provide beauty and functionality but also help conserve water and reduce the need for chemical fertilizers and pesticides, making them a more eco-friendly choice.
2. Design for Wind and Salt Tolerance
Coastal Virginia is known for its high winds, especially during storms, and its salty air, which can damage plants that are not salt-tolerant. When designing your landscape, it’s essential to incorporate plants that can withstand these challenging conditions. Many coastal native plants are already adapted to these elements, but strategic planning will further protect your garden.
- Windbreaks: One of the most effective ways to mitigate the effects of coastal winds is by planting windbreaks. Dense shrubs and trees can help protect more delicate plants from harsh gusts. Eastern Red Cedar is a great choice for this purpose due to its dense, evergreen foliage. Similarly, Inkberry Holly makes a great hedge that can act as a barrier against wind, salt, and spray.
- Create Microclimates: In some areas, you can create microclimates where more delicate plants can thrive. Use taller shrubs or trees as natural windbreaks around more sensitive plants. By strategically placing taller species, you create areas that are shielded from strong winds, giving your garden the chance to flourish.
- Salt-Tolerant Grasses: Coastal grasses like Little Bluestem and Seaside Goldenrod (Solidago sempervirens)help stabilize the soil and add texture to your landscape while thriving in salt-saturated environments. These grasses also help protect the soil from erosion, particularly along sandy or sloped areas.
- Raised Beds: Coastal soils tend to be sandy and have poor water retention. Raised garden beds can give you more control over the soil composition, allowing you to add organic matter, compost, and other soil amendments. This will help retain moisture, provide better drainage, and give your plants a more favorable growing environment.
3. Manage Stormwater Effectively
Coastal Virginia’s proximity to the ocean and the Chesapeake Bay means the region experiences heavy rainfall, storm surges, and flooding. These weather events can wreak havoc on your garden, causing erosion and waterlogging of your plants. Proper stormwater management is essential for protecting your landscape and preventing damage during storms.
- Rain Gardens: One of the most effective ways to manage excess water is by creating a rain garden. These shallow depressions are designed to collect rainwater runoff, allowing it to slowly infiltrate the soil. Planting moisture-loving species such as Virginia Sweetspire (Itea virginica) and Russian Sage will help absorb excess water and improve drainage.
- Swales and Berms: Swales are shallow ditches that can direct stormwater away from your house and toward areas where it can be absorbed into the soil. Swales planted with grasses such as Little Bluestem or Beach Grass (Ammophila breviligulata) are ideal for slowing down water and preventing erosion. Berms, which are mounds of earth, can be used in conjunction with swales to guide water in a specific direction and reduce water buildup in low-lying areas.
- Permeable Paving: To prevent stormwater runoff, consider using permeable materials for your patios, walkways, and driveways. Gravel, permeable pavers, and porous concrete allow water to pass through and soak into the ground, rather than running off into storm drains.
4. Sustainability in Coastal Landscapes
Designing a sustainable landscape is essential for protecting the environment and promoting ecological balance. Coastal landscapes are especially vulnerable to pollutants and erosion, so adopting sustainable practices in your garden can help protect local waterways and ecosystems.
- Water Conservation: One of the primary benefits of using native plants like Little Bluestem, Russian Sage, and Sweetbay Magnolia is their low water requirements once established. These plants are drought-tolerant and require minimal irrigation, which helps conserve water. Installing a drip irrigation system or rain barrels can also help manage water usage in your garden.
- Wildlife Habitat: Native plants like Eastern Red Cedar and Inkberry Holly support local wildlife, including birds, butterflies, and small mammals. By creating a habitat for these creatures, you not only increase biodiversity in your garden but also contribute to the health of the local ecosystem.
- Low-Maintenance Gardening: Sustainable landscapes require fewer chemicals and less frequent mowing. By selecting plants that are well-suited to the local climate and soil, you can reduce the need for chemical fertilizers, pesticides, and herbicides. Organic mulching and composting are also effective ways to improve soil health naturally.
5. Create a Coastal-Inspired Design
The beauty of coastal Virginia can be incorporated into your landscape design by using elements that reflect the region’s natural charm. Whether it’s a beach-inspired patio or a water feature that mimics the bay, these touches can enhance your garden’s aesthetic.
- Beach-Inspired Hardscaping: Use light-colored stones, shells, driftwood, and other natural materials to create pathways, garden borders, or decorative features that evoke the coastal landscape.
- Seaside Water Features: Adding a small pond, fountain, or waterfall to your garden can bring the peaceful sounds of water to your outdoor space. Choose a design that reflects the surrounding landscape, such as a tranquil koi pond or a bubbling water feature that mimics the sound of the ocean.
- Outdoor Living Spaces: Coastal living encourages outdoor activities, and creating spaces to relax and entertain is a great way to make the most of the area’s temperate climate. Consider adding a deck, pergola, or outdoor kitchen to your garden where you can enjoy the fresh air and scenic views.
