Pennsylvania’s climate spans humid summers, cold winters, and a mix of clay, loam, and acidic soils across USDA Zones 5 through 7. The wrong perennial selection means replanting every spring; the right one delivers color year after year without coddling.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent years comparing hardiness specifications, analyzing owner feedback across Pennsylvania’s varied microclimates, and studying horticultural data to narrow down what actually survives here.
This guide breaks down the top five proven performers for low-maintenance, season-long color. Whether you need a full-sun pollinator magnet or a shade-tolerant groundcover, you’ll find your match among the best perennials for pennsylvania that return reliably every spring.
How To Choose The Best Perennials For Pennsylvania
Picking perennials for Pennsylvania is not about picking the prettiest flower. The state spans three USDA hardiness zones (5, 6, and 7), and a plant that thrives in Philadelphia may rot or freeze in the Poconos. Focus on biology and site conditions before aesthetics.
Match the USDA Hardiness Zone First
Zone 5 covers northern and central PA, with winter lows between -20°F and -10°F. Zone 7 covers the southeastern corner, where lows rarely dip below 0°F. A perennial labeled “Zone 4–8” will survive anywhere in the state; a “Zone 7–9” plant will die in the first Erie winter. Always confirm the lower end of the range covers your specific geographic location.
Evaluate Sunlight and Soil Drainage
Most PA yards have heavy clay or acidic loam. Full-sun perennials require at least six hours of direct light per day; partial-shade plants need dappled light or morning sun with afternoon relief. Check the root structure: taproots handle clay better than fibrous mats in waterlogged soil. Creeping Jenny, for example, needs consistent moisture, while Echinacea tolerates drought once established.

In‑Depth Reviews
1. Proven Winners – Echinacea LAKOTA ‘Santa Fe’ (Coneflower)
This premium coneflower ships in a #1 container with fully rooted soil, meaning it can go straight into the ground the day it arrives—weather permitting. The mature height of 16 inches with an 18-inch spread makes it a compact choice for grouping in sunny borders or pollinator strips. Owner reports from PA confirm it survived Zone 6 winters and returned with heavy blooms in the second season.
The pink-orange flowers attract butterflies and hummingbirds while being naturally deer and rabbit resistant—a critical feature for yards bordering wooded PA areas. Multiple verified reviews highlight that the plant arrived with buds ready to open, and the foliage remained disease-free through humid summers. The three-star complaint about size appears tied to early-season shipping of smaller starter containers, not the mature plant potential.
For Pennsylvania gardens in Zones 5 through 7, this Echinacea requires well-drained soil and moderate watering until established. Its low-maintenance habit pairs well with salvias and black-eyed susans for a staggered bloom sequence from summer through fall.
What works
- Large, ready-to-bloom container plant
- Deer and rabbit resistant labels hold true for most yards
- Returns reliably in Zone 5-7 winters
What doesn’t
- Premium price for a single container
- Deer resistance can fail in heavy-pressure areas
- Some early shipments arrive smaller than expected
2. Perennial Farm Marketplace Lamium ‘Purple Dragon’ (Dead Nettle)
If your Pennsylvania yard has a shady corner where nothing seems to thrive, Lamium ‘Purple Dragon’ is the answer. This live perennial arrives in a #1 container with silver-variegated leaves edged in green, topped with deep purple flowers that appear in spring and return sporadically through fall. At only 4 to 8 inches tall, it works as a dense mat under trees or along north-facing foundations.
The special features here—deer resistance, rabbit resistance, and low maintenance—are backed by consistent owner feedback. One review noted it “thrived in heavy rain while other planters failed,” a key advantage for PA’s spring downpours. Another buyer mentioned the silvery foliage retained its color even in deep shade, and the plant attracted ladybugs without any pest issues. The packaging receives repeated praise for arriving with moist soil and intact limbs.
Partial shade is ideal, though morning sun with afternoon shade yields the heaviest flowering. It spreads moderately without being invasive, making it a safer groundcover choice than vinca or ivy for PA gardens that border wooded areas.
What works
- Excellent deer and rabbit resistance
- Fast-growing groundcover for dry shade
- Sporadic rebloom from spring to fall
What doesn’t
- Single container per purchase
- Flowers are less showy in deep shade
- Requires partial sun for best bloom density
3. Clovers Garden Black Eyed Susan (Rudbeckia) – 2 Live Plants
Black Eyed Susan is the quintessential Pennsylvania perennial, and this two-pack from Clovers Garden arrives in 4-inch pots with plants measuring 4 to 8 inches tall. The company uses a “10x Root Development” method that builds stronger root systems before shipping—a critical advantage when planting into PA’s heavy clay soils. The non-GMO, neonicotinoid-free label makes it safe for pollinator-friendly gardens.
The bright yellow petals with dark brown centers bloom from midsummer through early fall, with peak color in late August when many other perennials start fading. Owner feedback is overwhelmingly positive: plants arrived “SO healthy and green” within five days, with moist soil and no drooping. The one-star complaint about failure to return suggests the planting location may have been borderline for Zone 5 winters, but the variety is rated for all US zones including Zone 3.
These Rudbeckia grow 2 to 3 feet tall and need full sun—at least six hours daily—to produce the dense flower clusters Pennsylvania gardeners expect. They spread readily but stay clump-forming, making them appropriate for foundation plantings without overtaking neighboring perennials.
What works
- Two healthy plants in 4-inch pots at a fair price
- Strong root system for clay soil survival
- Prolonged bloom from midsummer through fall
What doesn’t
- Some plants failed to return in colder microclimates
- Requires full sun; disappointing in part shade
- Packaging can shift during transit
4. Gardening4Less 9-Pack Hosta Bare Root Perennial Plants
Hostas dominate Pennsylvania shade gardens for a simple reason: they ask for nothing and deliver reliable foliage year after year. This 9-pack of bare-root hostas from Gardening4Less offers the highest plant count in this roundup, making it the most economical way to cover large areas under trees or along north-facing beds. The variety likely includes green, purple, and white bloomers across different leaf shapes.
Owner reviews consistently report “roots galore” with active sprouting at arrival. Multiple buyers noted the roots were moist and healthy, and all nine plants established within a week of planting. Hardiness Zone 3 coverage means even the coldest PA microclimates—like the Poconos or Erie snowbelt—won’t harm them. The sandy soil recommendation suggests amending heavy clay with compost before planting.
Full shade is non-negotiable; hostas scorch in afternoon sun, especially during PA’s humid July afternoons. The lack of a specific variety name means you’re getting a mixed lot, which can produce different leaf sizes and colors. For a uniform look, consider buying named cultivars individually.
What works
- Best bulk value for large shade areas
- Rapid establishment within one week
- Zone 3 hardiness covers all PA locations
What doesn’t
- No variety or color guarantee on the mix
- Bare roots are smaller than potted equivalents
- Some roots may arrive dry if shipping is delayed
5. Creeping Jenny (Lysimachia nummularia) – 2 Plants Per Pack
Creeping Jenny is the fastest-matting perennial in this group, spreading up to 18 inches per plant with vibrant chartreuse foliage that brightens dark soil. This two-pack from The Three Company ships in 1-pint pots at 4 inches tall, ready for window boxes, rock walls, or erosion control on sloped PA properties. The “moneywort” nickname comes from its coin-shaped leaves, which cascade beautifully over container edges.
Owner sentiment is divided on packaging quality: several five-star reviews report “perfectly packaged” plants that thrived after a week, while one verified one-star review describes a small box designed for bulbs that allowed stems to snap. The plant itself is vigorous—one buyer noted growth within a week after reviving a wilted specimen in shade. Regular watering is mandatory; this is not a drought-tolerant groundcover for dry PA summers.
It grows in sun or partial shade, but the brightest chartreuse color requires at least four hours of direct sun. Invasive potential is moderate—contain it with edging or plant in containers to prevent it from overtaking smaller perennials.
What works
- Fast fill-in for bare spots and erosion areas
- Vibrant chartreuse color contrasts dark foliage
- Grows in sun or partial shade
What doesn’t
- Packaging inconsistency can damage delicate stems
- Needs consistent moisture; wilts in dry spells
- Can become invasive if not contained
Hardware & Specs Guide
USDA Hardiness Zone
Pennsylvania ranges from Zone 5a (-20°F) in the northern tier to Zone 7b (5°F) in the southeastern corner near Philadelphia. Every perennial you choose must have a lower zone rating that covers your specific area. A plant labeled Zone 4-9 will survive anywhere in the state; a Zone 7-9 plant will perish in a Pittsburgh winter. The five selections in this guide all carry ratings that cover at least Zones 5 through 7.
Light Requirements
Full-sun perennials (Rudbeckia, Echinacea) need six or more hours of direct sun daily. Shade-tolerant perennials (Hosta, Lamium) thrive with dappled light or morning sun only. Creeping Jenny sits in the middle: it needs at least four hours of sun to maintain its yellow-green color but will survive in partial shade. Matching light requirements to your yard’s exposure directly affects bloom density and foliage health.
Soil Type & Drainage
Most Pennsylvania yards have clay soil that holds moisture and warms slowly in spring. Bare-root hostas need amended soil with organic matter for drainage. Echinacea and Rudbeckia develop taproots that penetrate clay naturally. Creeping Jenny and Lamium prefer consistent moisture but will rot in standing water. Test your drainage by digging a 12-inch hole and filling it with water; if it takes longer than 12 hours to drain, raise the planting bed or amend heavily.
Deer & Pest Resistance
Deer pressure varies dramatically across PA—suburban Philadelphia deer are far more aggressive than rural Lancaster populations. Lamium and Echinacea carry deer-resistant labels that hold in moderate-pressure areas but fail when food is scarce. No plant is 100% deer-proof; rotating repellents or using physical barriers is the only guarantee. Hostas are deer candy unless protected, but the 9-pack’s low replacement cost softens the risk.
