What Are NJ Native Plants?

New Jersey’s native plants evolved in the region’s unique climate and soil conditions over thousands of years. They created beneficial relationships with local wildlife and help maintain healthy ecosystems throughout the state.

Definition of Native Plants

Native plants are species that naturally occur in a particular region without human introduction. In New Jersey, these plants developed over thousands of years in the state’s various habitats.

They adapted specifically to NJ’s climate conditions, soil types, and ecological relationships. Native plant species include trees like the Eastern White Pine and Red Maple, shrubs such as New Jersey Tea and Mountain Laurel, and wildflowers like Black-eyed Susan and Purple Coneflower.

These plants existed in New Jersey before European settlement. NJ natives evolved alongside local insects, birds, and mammals.

This co-evolution created interdependent relationships. These relationships form the foundation of New Jersey’s diverse ecosystems.

Benefits to New Jersey Ecosystems

Native plants provide essential food and shelter for local wildlife. For example, oak trees native to NJ support over 500 species of caterpillars, which become food for birds and other animals.

These plants require less maintenance once established. They typically need less watering, fewer pesticides, and minimal fertilization.

Native plants help prevent erosion and manage stormwater. Their deep root systems hold soil in place and absorb rainwater effectively.

They also support essential pollinators like bees, butterflies, and hummingbirds. The decline in pollinator populations makes growing native plants increasingly important for ecological health.

Key Characteristics of NJ Native Plant Species

NJ native plants show remarkable adaptation to local conditions. They tolerate the state’s hot, humid summers and cold winters better than many non-native species.

Many native plants feature drought tolerance once established and resistance to local pests and diseases. They provide seasonal interest through flowers, berries, or fall color.

The state’s native flora includes plants for every habitat type. From the Pine Barrens’ sandy acidic soil to the rich loam of northern forests, native options exist for every garden situation.

Some plants develop unique strategies to thrive. For instance, the Pitch Pine can resprout after fires, an adaptation to the natural fire cycles in the Pine Barrens region.

Native plants connect modern landscapes to New Jersey’s natural heritage. They reflect the state’s biodiversity and ecological richness.

Regions and Ecoregions of New Jersey

New Jersey contains distinct natural regions that support diverse plant communities. These ecoregions vary in soil types, elevation, and climate, creating unique habitats for native plants across the state.

Ridge and Valley

The Ridge and Valley region occupies northwestern New Jersey. It features parallel mountain ridges and valleys running northeast to southwest.

This region has limestone valleys with alkaline soil that supports unique plant communities. Many calcium-loving plants thrive here, including:

• Walking fern (Asplenium rhizophyllum)
• Yellow lady’s slipper (Cypripedium parviflorum)
• Northern prickly ash (Zanthoxylum americanum)

The valleys contain rich agricultural land. The ridges support oak-hickory forests.

Kittatinny Mountain, the most prominent ridge, hosts plant species more typically found in the Appalachian Mountains. Spring wildflowers bloom abundantly in this region’s deciduous forests.

These include trillium, bloodroot, and various violets that emerge before the tree canopy leafs out.

Highlands

The New Jersey Highlands form a geological province of ancient, hard bedrock crossing the state’s northern portion. This region’s rocky, acidic soils support distinctive plant communities adapted to harsh conditions.

Key native plants include:

• Chestnut oak (Quercus montana)
• Mountain laurel (Kalmia latifolia)
• Lowbush blueberry (Vaccinium angustifolium)

The Highlands contain critical watershed areas that supply drinking water to millions of New Jersey residents. Wetlands in this region harbor unique species like swamp azalea and skunk cabbage.

Higher elevations feature northern hardwood forests with sugar maple, beech, and yellow birch trees. These forests resemble those found further north in New England.

The region’s rocky outcrops create microhabitats for specialized plants like rock polypody fern and early saxifrage.

Pinelands

The Pinelands (or Pine Barrens) cover over one million acres in southern New Jersey. This globally rare ecosystem sits atop sandy, acidic, nutrient-poor soil that creates challenging growing conditions.

The region’s signature plant is the pitch pine (Pinus rigida). Pitch pines have adapted to survive periodic wildfires.

These trees often have multiple trunks and can resprout after fire damage. Other distinctive Pinelands plants include:

• Pygmy pitch pines (stunted pine forests)
• Sheep laurel (Kalmia angustifolia)
• Pine Barrens gentian (Gentiana autumnalis)
• Curly-grass fern (Schizaea pusilla)

Cedar swamps with Atlantic white cedar trees form in low-lying areas. These wetlands support carnivorous plants like sundews and pitcher plants that extract nutrients from insects rather than the poor soil.

Barnegat Bay Watershed

The Barnegat Bay Watershed encompasses about 660 square miles in Ocean County. This coastal ecosystem includes the bay itself, surrounding marshes, and the rivers and streams that feed into it.

Salt marshes line much of the bay, dominated by:

• Smooth cordgrass (Spartina alterniflora)
• Salt hay grass (Spartina patens)
• Black needlerush (Juncus roemerianus)

These marshes provide crucial habitat for wildlife and help filter pollutants before they reach the bay. They also protect inland areas from storm surges and flooding.

Freshwater wetlands occur where streams enter the bay. These areas support plants like sweet pepperbush, swamp azalea, and various sedges and rushes.

Upland areas within the watershed contain pine-oak forests similar to the Pinelands. Development pressure threatens many native plant communities in this region.

Creating a Jersey-Friendly Native Landscape

Transforming your yard with New Jersey native plants creates beautiful, sustainable spaces that support local wildlife. Native landscapes thrive in our climate and soil without much intervention.

Native Plant Landscaping Strategies

Start by assessing your yard’s sunlight, soil type, and moisture levels. These factors help you choose the best native plants for each area.

Group plants with similar needs together to create cohesive garden zones. Layer your landscape with trees, shrubs, and ground covers to mimic natural ecosystems and provide wildlife habitats.

Native oak trees support many butterfly and moth species. Shrubs like bayberry offer shelter for birds.

Plant in drifts or clusters instead of single specimens. Groups of 3-7 plants of the same species create visual impact and better support pollinators.

The Jersey-friendly yards program suggests including at least 70% native species in your landscape design.

Using Native Plants for Soil Erosion Control

Native plants prevent soil erosion with their extensive root systems. Little bluestem grass, for example, develops roots 5-8 feet deep, anchoring soil on slopes.

For wet areas prone to runoff, plant native sedges and rushes. These absorb excess water and stabilize soil with fibrous roots.

Pennsylvania sedge does well in shady spots, while switchgrass thrives in sunny locations.

Rain gardens with moisture-loving natives like cardinal flower and blue flag iris capture stormwater runoff. These gardens slow water movement and let it soak into the ground.

For steep slopes, spread groundcovers like wild strawberry or barren strawberry. These plants form living mulch that protects soil during heavy rains.

Deer Resistant and Low-Maintenance Options

Many New Jersey homeowners struggle with deer damage, but some native plants naturally resist browsing. Aromatic plants like mountain mint and bee balm deter deer and attract beneficial insects.

Prickly or fuzzy-textured plants also resist deer. Christmas fern stays green year-round and is rarely eaten by deer. American holly offers evergreen structure with spiny leaves.

Low-maintenance natives need less watering, fertilizing, and pest control. Drought-tolerant plants like butterfly weed and prairie dropseed rarely need extra water once established.

Deer-Resistant Native Plant Options:

• New Jersey tea (Ceanothus americanus)
• Anise hyssop (Agastache foeniculum)
• Goldenrod varieties (Solidago spp.)
• Bayberry (Myrica pensylvanica)

Supporting Local Wildlife and Pollinators

New Jersey native plants provide food and shelter for local wildlife. These plants evolved with native animals and support our ecosystem.

Enhancing Habitats for Native Bees
