Native Plants by Ecoregion: A Guide

Native Plants by Ecoregion: A Guide

Native plants are essential for creating low-maintenance landscapes that support local ecosystems. They save water, reduce upkeep, and attract wildlife like bees and birds. To choose the right plants, you need to identify your ecoregion - an area defined by its soil, climate, and native species. This guide helps you:

  • Step 1: Find your ecoregion using tools like the EPA Ecoregions Map or local extension office resources.
  • Step 2: Select plants suited to your region - e.g., Eastern Redbud for forests, Little Bluestem for plains, or Barrel Cactus for deserts.
  • Step 3: Follow planting tips like soil testing, proper spacing, and watering schedules to ensure success.

Native plants thrive naturally, requiring fewer resources and benefiting the environment. Use this guide and tools like the Lady Bird Johnson Wildflower Center database to start your eco-friendly garden today.

Native Landscaping 101: Choosing Plants for Your Ecoregion

Finding Your Ecoregion

Knowing your ecoregion helps you choose the right native plants by considering the entire ecosystem, not just temperature ranges like hardiness zones do.

Tools to Identify Your Ecoregion

The Environmental Protection Agency (EPA) provides helpful resources for pinpointing your ecoregion:

  • EPA Level III Ecoregions Map: This interactive map, available on the EPA's website, divides North America into 105 regions.
  • USGS Ecoregions Database: Offers in-depth geological and ecological data for each area.
  • Local Extension Office Tools: Many state extension offices provide mapping tools tailored to their specific regions.

Combine these tools with local conservation data for a clearer picture. Thrive Lot’s designers, for example, use these resources to create personalized native landscapes.

What Defines an Ecoregion?

Ecoregions are shaped by several environmental factors that influence which plants will thrive:

Factor Role in Plant Selection
Soil Composition Impacts nutrient levels and water drainage.
Annual Rainfall Determines water needs and plant spacing.
Temperature Range Affects plant hardiness and growing seasons.
Elevation Alters wind exposure and temperature patterns.
Native Wildlife Drives plant-pollinator and other ecological relationships.

For instance, the tall grass prairies of the Great Plains rely on specific soil microbes that aren't found in the acidic soils of the Northeast.

Ecoregion Myths Debunked

Myth 1: USDA hardiness zones are the same as ecoregions.
Reality: Hardiness zones only focus on minimum temperatures, while ecoregions consider soil, rainfall, wildlife, and more.

Myth 2: Plants from similar climates will always thrive.
Reality: Factors like soil type and local wildlife interactions are just as important as climate.

Myth 3: Ecoregion boundaries are fixed.
Reality: Transition zones exist where characteristics gradually shift, especially in areas with diverse elevations or microclimates.

Even if a plant survives your winter, it may fail without the right soil or local pollinators. Once you’ve identified your ecoregion, you’ll be ready to dive into native plant recommendations tailored to your area.

Native Plants by Region

Once you’ve identified your ecoregion, use these native plant suggestions to match your local soil and climate. These recommendations will guide you in creating a garden that thrives naturally and supports the environment.

Plants for Eastern Forests

The Eastern Temperate Forest region is home to woodland species that grow well in partial shade and acidic soils:

Plant Type Recommended Species Key Benefits
Trees Eastern Redbud, Flowering Dogwood Spring blooms and habitat for birds
Shrubs Mountain Laurel, Winterberry Holly Year-round beauty and food for wildlife
Perennials Wild Geranium, Black-Eyed Susan Long blooming periods and pollinator support
Ground Cover Wild Ginger, Christmas Fern Erosion control and shade tolerance

Layered plantings that mimic natural forest ecosystems work best with these species.

Plants for Plains Areas

The Great Plains region requires plants that endure strong winds and changing rainfall. Focus on deep-rooted species to stabilize the soil:

Plant Type Recommended Species Drought Tolerance
Grasses Little Bluestem, Buffalo Grass Very High
Flowers Purple Coneflower, Butterfly Milkweed High
Ground Cover Prairie Smoke, Wild Strawberry Medium-High

These plants typically take 12–18 months to establish their roots and can often thrive with just natural rainfall.

Plants for Desert Regions

Desert plants are built for survival in low-rainfall environments. Choose species that match your desert’s specific conditions:

Plant Type Water Needs (inches/year) Maintenance Level
Barrel Cactus 4–8 Very Low
Desert Marigold 8–12 Low
Creosote Bush 6–10 Very Low
Desert Willow 12–16 Low

Proper spacing is critical - keep shrubs 3–5 feet apart and trees 8–10 feet apart to minimize competition for water.

For personalized advice, consult local native plant experts or networks like Thrive Lot to design a garden suited to your specific region.

Planting and Care Guide

Once you've chosen your native plants and identified your ecoregion, it's time to prepare your garden and get planting.

Site Preparation Steps

Start by checking your soil's composition and drainage. A soil test from your local extension office can help you figure out the pH levels and nutrient content. Native plants generally do well in soils with a pH between 6.0 and 7.0.

Preparation Task Timing Purpose
Soil Testing Early spring or fall Identify pH and nutrient needs
Weed Removal 2–3 weeks before planting Minimize competition for resources
Soil Amendment 1–2 weeks before planting Enhance drainage and structure
Site Marking 1 week before planting Plan plant spacing and layout

Planting and Care Methods

During the first 12–18 months, native plants need attentive care to help them establish. Water deeply but less often to promote strong, deep roots. Spread a 2–3 inch layer of organic mulch around your plants, but leave space around the stems to avoid rot.

Here’s a simple watering guide to follow:

Plant Age Watering Frequency Amount per Session
First Month Every 2–3 days 1–2 gallons per plant
Months 2–6 Weekly 2–3 gallons per plant
After 6 Months Based on rainfall Adjust as needed

Managing Problem Plants

Invasive species can be a major threat to your garden. Check regularly for unwanted plants and use chemical-free methods to remove them. For small outbreaks, hand-pulling works well. For larger areas, mechanical removal can be more effective.

Creating a 3-foot buffer zone around young native plants can help reduce competition. Inspect your garden monthly during the growing season for any signs of stress or invasive growth. Take photos of problem areas to track changes and improve your management approach over time.

Help and Information

Plant Search Tools

Looking for native plants? The Lady Bird Johnson Wildflower Center offers an extensive database to help you find plants that match your state, growing conditions, and other preferences. Check it out at wildflower.org/plants.

Another great resource is the USDA PLANTS Database (plants.usda.gov), which provides detailed maps and scientific data on native species.

Resource Name Best For Key Features
Wildflower Center Database Plant selection Growth needs, bloom times, and wildlife value
USDA PLANTS Distribution data Range maps, taxonomy, and threatened species
Calscape California natives Local nursery stock, water needs, and images
NatureServe Explorer Conservation status Habitat details and population trends

Local Plant Groups

Native plant societies are great for local expertise. Many state organizations host events like monthly meetings, workshops, and plant sales featuring species from the area. They often organize guided walks to help identify native plants and offer consultations for garden planning.

For example, the California Native Plant Society has 35 regional chapters, each focusing on the unique plants of its area. Whether you're looking for advice or local events, these groups are an excellent resource.
