Native Plant Garden Design: Embracing Local Flora

ByEmily Johnson

There are many benefits of using native plants in garden design. Native plants are those that occur naturally in a region in which they evolved and are naturally adapted to local environmental conditions and support native wildlife. Because native plants are already acclimated to local soil, rainfall and temperature conditions, they typically require less watering and maintenance once established (Why Native Plants Matter). By embracing native plants in garden design, we can support our local ecosystems and wildlife.

Native plants play an essential role in maintaining the biodiversity and balance of ecosystems. Their deep root systems help prevent soil erosion and filter stormwater, while their flowers, fruits and foliage provide food and shelter for native wildlife and pollinators. Native plants also support beneficial insects that naturally keep pest populations in check (Why Native Plants Matter).

Overall, using native plants in garden design provides vital habitat and resources that support local wildlife, preserves a sense of natural heritage and place, conserves water and reduces maintenance. By embracing native flora in our gardens, we can sustain local ecosystems while creating beautiful, nature-inspired landscapes.

Native Plant Basics

A plant is considered native to an area if it has evolved and occurs naturally in a particular region without human introduction Native Plants. Native plants have adapted over time to local environmental conditions such as soil, rainfall, climate, and pests. They form the foundation of local ecosystems and food webs.

Key characteristics of native plants include:

  • They are adapted to local soils and climate
  • They have co-evolved with native wildlife and form vital ecological relationships
  • They require less maintenance as they are resistant to most local pests and diseases
  • They preserve the local sense of place and cultural heritage

Native plants differ from non-native plants, which are species introduced by humans either intentionally or accidentally. Non-native species often lack natural predators in their new environment and can become invasive, disrupting local ecosystems. Using native plants helps preserve biodiversity and provides numerous ecological benefits.

Selecting Native Plants

When choosing native plants for your garden, it’s important to select varieties that are well-suited to your specific region and growing conditions. The Xerces Society provides excellent region-specific resources including native plant lists tailored to support pollinators.

Consider factors like your USDA Hardiness Zone, the amount of sunlight an area receives, and the soil moisture and pH when selecting plants. Resources like the Michigan State University Native Plants and Ecosystem Services Plant Finder tool allow you to filter potential plant choices by these parameters.

Some native plants that make excellent choices for home gardens in many areas include black-eyed susans (Rudbeckia spp) and coneflowers (Echinacea spp) for pollinator-friendly sun gardens, and ferns, wild ginger (Asarum canadense), and woodland phlox (Phlox divaricata) for shade gardens.

Consult local native plant nurseries or your state’s native plant society to choose species and cultivated varieties that will thrive where you live.

Design Principles

When designing a native plant garden, it’s important to apply basic principles like balance, focalization, proportion, repetition, rhythm, simplicity, transition and unity to create an aesthetically pleasing space. You can combine native plants of different textures, colors and heights to achieve visual interest. According to How to Design a Native Plant Garden – Dyck Arboretum, you should “use swaths of grasses and wildflowers to create movement and serpentine lines.” Curving beds with repeating patterns of complementary plants make the garden feel more organic and naturalistic.

You can also create focal points like specimen trees, large rocks or benches to draw the eye. Using proportion is key – don’t overwhelm a small space by planting huge shrubs or trees. Gradually transition from tall plants in the back down to low groundcovers in front for good scale and hierarchy. Simplicity and unity come from limiting the plant palette so there is cohesion. The overall effect should feel pleasantly designed yet still reflect the local native landscape.

Installing Native Plants

Proper preparation is crucial for successfully establishing native plants. First, prepare the soil by removing any existing lawn or invasive weeds, and turn over the top 4-8 inches to loosen any compacted layers (https://grownative.org/learn/native-garden-installation-toolkit/). Most native plants thrive in poor to average soils, so amendments usually aren’t necessary. However, you can mix in 1-2 inches of compost to improve water retention and nutrients. Avoid over-amending the soil, as this can cause native plants to underperform.

When planting, dig each hole 2-3 times wider than the root ball but no deeper. Native plants have deep root systems and planting too deep can cause failure. Carefully place each plant in its hole and backfill with the native soil. Water thoroughly after planting to eliminate any air pockets. Proper planting ensures the root ball makes good contact with the surrounding soil (https://www.marthastewart.com/8117751/native-plant-garden-tips).

After installation, water native plants regularly for the first 3 months to encourage deep root establishment. Then you can gradually reduce watering, allowing plants to adapt to natural rainfall patterns. Once established, most natives only need supplemental water during drought conditions. Proper planting techniques and post-installation care set your native garden up for success.

Maintaining Native Gardens

Native gardens require less maintenance than traditional ornamental gardens, but some ongoing care is still needed for them to thrive. Native plants are adapted to their local climate and soil conditions, so they typically do not require fertilization, frequent watering or soil amendments once established (Rethinking Native Plant Maintenance, GoodNatured). In fact, over-fertilizing and over-watering native plants can do more harm than good.

The main maintenance tasks for native gardens include occasional weeding, pruning, mulching and irrigation during drought periods. It’s important to identify and remove any invasive weeds that may compete with the native plants. Light mulching helps conserve moisture and suppresses weeds. Pruning of dead stems promotes fuller, healthier growth. Providing some irrigation during the first 1-2 years and during drought allows the native plants to develop deep root systems (Native Landscape Care Calendar, GrowNative).

Native gardens also provide excellent habitat for pollinators and other beneficial wildlife. Choosing a diversity of native plants with staggered bloom times supplies nectar sources all season. Leaving seed heads and hollow plant stems over winter gives insects and birds important shelter. Minimizing pesticide use protects pollinators and other species (Native Landscape Care Calendar, GrowNative).

While native plants have natural defenses against insects, some invasive pests may occasionally need control. Always use the least toxic methods when dealing with pests. Hand-picking large pests, using insecticidal soaps or oils, or introducing beneficial predator species can help keep pest populations in check.

Landscape Uses

Native plants can be incorporated into a wide variety of landscape applications to create beautiful, regionally appropriate spaces. Some ideas for native plant gardens include:

Rock Gardens

Rock gardens provide the perfect opportunity to showcase delicate native wildflowers and grasses that thrive in rocky, fast-draining soil. Species like columbine, stonecrop, and prairie dropseed are wonderful choices for rock gardens.

Rain Gardens

Rain gardens use native plants adapted to periodic flooding to absorb and filter runoff from roofs, driveways, and patios. Some excellent native plants for rain gardens include blue lobelia, swamp milkweed, and blue flag iris. Visit https://grownative.org/learn/native-landscape-plans/ for examples.

Meadows

Native meadow gardens create habitat while eliminating the need to mow. Tallgrass prairie species like big bluestem, purple coneflower, and goldenrod can be used to establish mini-meadows and enjoy waves of color through the seasons.

Consult a local native plant nursery or landscape designer for more inspiration on incorporating native plants into rock gardens, rain gardens, meadow landscapes, and more.

Overcoming Challenges

Native plants require a different care approach than ornamental varieties you may be used to. Here are some common challenges when starting a native plant garden and how to troubleshoot them:

Selecting the wrong plants is a common mistake. Make sure to choose species that are native to your specific region and match your site’s sunlight, soil type, and moisture levels. Consider the mature height and spread of plants to design an appropriate layout and allow enough space between plants. Refer to resources like the USDA’s native plant database or consult local nurseries. As noted by My Home Park, mismatched heights and spreads lead to overcrowding.

Weed control is crucial, as native plants can be sensitive to competition. Mulch heavily to suppress weeds and hand pull regular to keep them under control. Include native groundcovers like wild ginger or goldenstar to fill spaces and prevent weeds. The blog Monarch Gardens emphasizes using dense plantings and groundcovers to outcompete weeds.

Follow design principles to group plants thoughtfully and allow them room to thrive. Map out shapes and clusters on paper first. Mass plantings of 3-5 plants per species makes a bolder statement. Assess soil needs and amend if necessary to give plants their preferred growing conditions.

With good plant selection and care methods, native plants can be resilient. But be prepared to adapt and problem-solve over time as you learn what works for your unique landscape.

Sourcing Native Plants

Native plants can often be purchased from local native plant nurseries, native plant sales, or native plant catalogs. Here are some options for sourcing native plants in the United States:

Retail native plant nurseries are a great option for finding a wide selection of native plants local to your area. Some nurseries to check out include:

Native plant sales and swaps are another way to get native plants, often at lower cost. Check with local native plant societies, nature centers, or conservation groups to find native plant sales in your area.

Mail order native plant catalogs allow you to order plants and have them shipped to your door. Some popular options include Prairie Moon Nursery, Prairie Nursery, and Native American Seed.

Consider sourcing plants from your local region for the best results. Check nurseries within a 100-200 mile radius of where you live for native plants acclimated to your specific environment.

Embrace the Local Flora

Native plant gardens provide many benefits compared to traditional landscaping with non-native plants. Native plants are adapted to local environmental conditions, so they require less water, saving time, money, and freshwater reserves (https://www.audubon.org/content/why-native-plants-matter). They have also evolved alongside native pollinators and wildlife, providing vital food and habitat (https://www.fs.usda.gov/wildflowers/Native_Plant_Materials/Native_Gardening/index.shtml). In addition, native plants need little to no fertilizers or pesticides, making them a sustainable, eco-friendly choice (https://www.cnps.org/gardening/why-natives/benefits-of-california-native-plants).
