35 Pennsylvania Landscaping Ideas for Philly, Pittsburgh & the Poconos
From Philadelphia row homes to Pocono mountain retreats. Mountain laurel gardens, terraced hillsides, and deer-resistant designs for every PA region.
Philadelphia & Southeast PA (Zones 6b–7a)
Hot humid summers (95°F+), mild winters (10–20°F lows), 45" rain/year, clay-loam soil, urban heat island in Philly proper, historic row homes with minimal yards
Philly Row Home Courtyard
For Philadelphia's iconic row homes with 10×10 ft back courtyards: vertical wall gardens (ferns, hostas in wall pockets), a single Japanese maple specimen, bluestone patio, and container gardens for seasonal color.
Main Line Classic Estate
For Philadelphia's affluent Main Line suburbs: a formal English-style garden with boxwood hedges, perennial borders (peony, iris, delphiniums), sweeping lawn, and mature specimen trees (American elm, pin oak).
SE PA Native Woodland Edge
Southeast PA's Piedmont forests inspire this design: redbud understory trees, mountain laurel (PA state flower!), native azaleas, Christmas ferns, and wild ginger groundcover under oak canopy.
Philadelphia Rain Garden
Philadelphia's aging stormwater system benefits from rain gardens: cardinal flower, swamp milkweed, blue flag iris, and Joe-Pye weed absorb roof runoff while creating habitat. City rebates available through Philadelphia Water.
Pittsburgh & Southwest PA (Zones 6a–6b)
Four distinct seasons, 38" rain/year, hilly topography (terracing required), acidic soil from historic coal mining, frequent overcast, shorter growing season than Philly
Pittsburgh Hillside Terrace
Pittsburgh's famous hills require terraced retaining walls: natural Pennsylvania bluestone walls with creeping phlox cascading over edges, ornamental grasses on upper terrace, and rhododendrons thriving in acidic soil.
Steel City Modern Backyard
A contemporary design for Pittsburgh's revitalized urban neighborhoods: Cor-ten steel (Pittsburgh steel heritage!) planters, gravel hardscape, ornamental grasses, and a sculptural smokebush specimen.
Southwest PA Cottage Garden
A classic cottage garden for Pittsburgh suburbs: David Austin roses, catmint, delphiniums, foxgloves (thrive in acidic soil), and a white picket fence with climbing roses. Beautiful May–September.
Laurel Highlands Native Garden
Inspired by PA's Laurel Highlands: native mountain laurel mass planting (8+ shrubs for impact), serviceberry, native azaleas, and autumn ferns create a stunning PA woodland aesthetic.
Poconos & Northeast PA Mountains (Zones 5a–6a)
Cold mountain climate (zone 5a at elevation), 50" rain + 60" snow annually, short growing season, acidic rocky soil, stunning fall foliage, second-home market
Poconos Mountain Rhododendron Garden
The Poconos' acidic soil is PERFECT for rhododendrons: mass plantings of Catawba rhododendron (pink/purple), PJM rhododendron (early spring magenta), and native azaleas create a May spectacle.
NE PA Alpine Rock Garden
For Poconos properties with natural rock outcrops: creeping phlox, sedum, hens-and-chicks, and cushion plants fill rock crevices. Add native columbine for vertical interest. Zero irrigation needed.
Pocono Lake House Naturalized Yard
For lakefront properties: naturalized landscape with native white pines, birch groves, blueberries, wintergreen groundcover, and ferns. Looks like untouched forest but is carefully designed for low maintenance.
Pocono Four-Season Color
Designed for year-round Pocono cabin visits: spring bulbs, summer astilbe and hostas, fall maples and burning bush (spectacular in Poconos), winter evergreens and red-twig dogwood for structure.
Central & Rural PA — Amish Country (Zones 5b–6b)
Agricultural heartland (Lancaster, York counties), excellent loam soil, rolling farmland, significant deer pressure, traditional aesthetic preferred, four-season extremes
Lancaster County Farmhouse Landscape
Traditional farmhouse aesthetic: split-rail fencing, sweeps of daylilies and black-eyed Susan, a kitchen herb garden, heirloom roses, and a classic red barn backdrop. Timeless Pennsylvania style.

Pennsylvania Landscaping FAQs
What are the best plants for Pennsylvania landscaping?
Pennsylvania's diversity (zones 5a–7a) creates varied options. Statewide winners: mountain laurel (state flower, thrives in PA's acidic soil), eastern redbud, white pine, serviceberry, purple coneflower, black-eyed Susan, and native ferns. Philadelphia area (zone 7a) can grow crape myrtles and southern magnolia. Poconos (zone 5a) excel with cold-hardy rhododendrons, birch, and alpine plants. Match plants to your PA zone.
How do I landscape Pennsylvania's hilly terrain?
PA's rolling hills (especially Pittsburgh, Poconos, and central PA) require terracing. Solutions: (1) Build retaining walls in natural PA bluestone or concrete block faced with stone, (2) Terrace at 3–4 foot height increments — safer and more stable, (3) Plant groundcovers on slopes (creeping phlox, junipers, pachysandra) to prevent erosion, (4) Use cascading plants over wall edges (creeping Jenny, candytuft), (5) On very steep slopes (30%+), consult an engineer before building walls over 4 feet.
What plants are deer-resistant in Pennsylvania?
PA has severe deer pressure, especially in rural counties and suburbs near forests. Most reliable deer-resistant plants: daffodils (deer won't touch them), catmint, Russian sage, yarrow, lamb's ear, thorny roses (rugosa), lavender, ornamental onions, and most ornamental grasses. Deer will eat almost anything when starving in winter, but these are last resort. Fence vegetable gardens completely — 8 feet tall minimum.
Can I grow rhododendrons in Pennsylvania?
Yes — Pennsylvania is EXCELLENT for rhododendrons. PA's acidic soil (pH 5.0–6.0 in most areas) is ideal. Mountain laurel (PA state flower) and native Catawba rhododendron thrive statewide. PJM rhododendron is zone 5-hardy (Poconos). Best performance: Poconos and Laurel Highlands (natural range), but they succeed anywhere in PA with acidic soil and part shade. Avoid alkaline soils (parts of southeast PA) without amending.
What's the best time to plant in Pennsylvania?
Best planting windows: Trees and shrubs: March–May (spring) or September–November (fall). Fall is preferred — cooler, more rain, less transplant stress. Perennials: April–May or September–October. Avoid mid-summer planting (July–August heat stress). Bulbs: September–October for spring bloom. Cool-season grass (fescue): September for best establishment. Zone 5 PA (Poconos): favor spring planting to give plants a full season before winter.
