Types Of Native Groundcovers For Pennsylvania Garden Design

Why choose native groundcovers in Pennsylvania gardens?

Native groundcovers provide ecological, aesthetic, and practical benefits that non-native groundcovers often cannot match. In Pennsylvania, native species are adapted to local climate, soil types, seasonal cycles, and local insect and bird communities. They require less water and fertilizer once established, resist local pests and diseases better, and support pollinators, ground-nesting bees, and wildlife that have evolved in this region.
Native groundcovers also help prevent erosion on slopes, reduce weed pressure when established, and create cohesive, place-based garden designs that change through the seasons with spring ephemerals, summer foliage, and autumn seedheads.

Key design considerations before choosing groundcovers

Select groundcovers based on these overriding factors rather than appearance alone. Mismatches are the most common reason plantings fail.

Native groundcovers for dry to well-drained sunny sites

These plants perform well in hot, sunny spots, rock gardens, thin soils, and along pathways where drought tolerance is important.

Sedum ternatum (Woodland stonecrop)

Sedum ternatum is a low-growing succulent relative that tolerates thin soils and seasonal drying despite its common woodland association. It produces clusters of white star-shaped flowers in spring and spreads slowly by short stolons.

Phlox subulata (Moss phlox) and Phlox stolonifera (Creeping phlox)

Phlox subulata prefers very sunny, well-drained sites and creates a carpet of color in spring. Phlox stolonifera is more woodland-tolerant and handles some shade. Both provide early-season nectar for native bees.

Fragaria virginiana (Wild strawberry)

A hardy, low mat-forming groundcover with small edible fruit and attractive spring flowers. It tolerates sun to part shade and a range of soils but prefers good drainage.

Native groundcovers for moist to wet or seasonally wet sites

Certain native groundcovers are adapted to consistently moist soils, stream edges, and low garden basins. They help stabilize soil and tolerate occasional flooding.

Carex lurida and Carex pensylvanica (Sedges)

The sedge family (Carex spp.) contains many excellent native groundcovers. Carex pensylvanica (Pennsylvania sedge) is a fine-textured, low-growing sedge that forms a soft lawn substitute in dry to mesic shade. Carex lurida is taller and handles wetter soils and seasonal inundation.

Lysimachia nummularia relatives avoided; instead consider Mitchella repens (Partridgeberry)

Mitchella repens is a creeping, evergreen groundcover of acid, shaded woodland soils. It produces paired white flowers followed by red berries that persist into winter and feed birds.

Maianthemum canadense (Canada mayflower)

A spring ephemeral that forms colonies of glossy leaves and tiny white flowers; it thrives in cool, moist shade and makes good naturalized carpets beneath trees and shrubs.

Native groundcovers for shady woodlands and understories

Shade-tolerant natives provide lush foliage where lawn will not grow. Choose groundcovers that appreciate leaf litter and moderate moisture.

Asarum canadense (Wild ginger)

Wild ginger forms dense, low mats of rounded, glossy leaves and produces an unusual maroon-brown flower hidden near the soil surface in spring. It spreads slowly by rhizomes and is excellent for deep shade.

Heuchera americana (Alumroot)

Heuchera offers attractive foliage in a range of textures and provides airy spikes of flowers attractive to pollinators. Native alumroot tolerates part shade and well-drained soils.

Viola sororia (Common blue violet)

Blue violets are versatile, forming colonies in shade or partial sun and providing important early-season nectar for native bees and larval food for fritillary butterflies.

Small evergreen and winter-interest natives

For year-round groundcover, include some evergreen or semi-evergreen species that keep winter structure and color.

Gaultheria procumbens (Eastern teaberry / Wintergreen)

Low growing, aromatic, evergreen groundcover with glossy leaves and red berries. Prefers acidic, well-drained but moist soils and heavy shade to part shade.

Vaccinium angustifolium (Lowbush blueberry)

Forms small clonal patches that offer spring flowers, summer fruit for wildlife, and fall color. Requires acidic soils but adds year-round interest.

Practical planting and maintenance steps

Follow methodical steps to give native groundcovers the best chance of successful establishment. A clear plan at planting reduces long-term maintenance.

  1. Assess site conditions: light, moisture, soil texture, pH, and existing vegetation.
  2. Prepare the bed: remove invasive plants and turf where necessary. Lightly cultivate to break compaction but retain topsoil structure.
  3. Amend only when needed: add organic matter for very poor soils; avoid heavy fertilization that favors weeds.
  4. Plant in masses and groups: most groundcovers look better and establish faster in groups rather than as single scattered plants.
  5. Mulch judiciously: use a thin 1-2 inch organic mulch at planting to conserve moisture and suppress weeds, but avoid smothering low evergreen leaves.
  6. Water regularly during the first season: establish roots with deep, infrequent watering rather than daily shallow watering.
  7. Monitor and thin: divide congested patches of spreading groundcovers every 3-5 years to maintain vigor and reduce disease risk.
  8. Control invasives early: remove non-native aggressive species (e.g., Vinca minor, Pachysandra terminalis) that can outcompete natives.

Combining groundcovers for layered interest and resilience

A resilient planting strategy mixes species with different growth habits, bloom times, and textures. Combine a low evergreen (e.g., Gaultheria procumbens) with spring ephemerals (Asarum, Maianthemum), mid-season bloomers (Heuchera, Phlox), and edible or wildlife-supporting species (Fragaria, Vaccinium).
Interplanting also reduces bare soil time, increases biodiversity and pollinator resources through the season, and creates a more naturalized look that resists erosion and weed invasion.

Wildlife and ecological benefits to emphasize

Native groundcovers do more than look attractive. They:

Design with an ecological lens: group species to provide continuous bloom from spring through fall and include host plants for local butterfly species if your goal is to support native insect populations.

Practical takeaways for Pennsylvania gardeners

Choosing native groundcovers is an investment in resilient, ecological landscape design. When you match plants to the specific conditions of your Pennsylvania site and manage establishment carefully, native groundcovers will reward you with low-input beauty, wildlife value, and enduring soil protection.
