Best Low Maintenance Perennials For Pennsylvania
These perennials are chosen for their ability to thrive in Pennsylvania’s USDA zones 5 to 7. They need little water once established, resist most pests, and come back year after year. Each plant fits a specific niche in your garden, from full sun to deep shade.
Top Sun-Loving Choices
If your yard gets at least six hours of direct sun, these plants are your best friends. They handle heat and dry spells without complaint.
- Black-Eyed Susan (Rudbeckia hirta): This native flower blooms from July to frost. It tolerates poor soil and drought. Deadheading extends blooms, but it’s not required. It self-seeds moderately, so you get more plants over time.
- Purple Coneflower (Echinacea purpurea): A classic for a reason. It attracts pollinators, resists deer, and thrives in lean soil. Cut back spent stems in spring for a tidy look. It naturalizes well in meadows.
- Sedum ‘Autumn Joy’: This succulent perennial needs almost no water. Its fleshy leaves store moisture, and its pink flowers turn copper in fall. It stays upright and looks good even in winter.
- Russian Sage (Perovskia atriplicifolia): This plant laughs at drought and poor soil. Its lavender-blue spikes add airy texture. Cut it back to a few inches in early spring. It spreads slowly but is easy to control.
- Daylily (Hemerocallis): Not a true lily, but a workhorse. It blooms in waves, tolerates clay, and spreads into dense clumps. Divide every few years if you want, but it’s not necessary for health.
Shade-Tolerant Favorites
Shade gardens in Pennsylvania can be challenging due to tree roots and dry soil. These perennials handle low light and competition from trees.
- Astilbe (Astilbe spp.): Perfect for moist, shady spots. Its feathery plumes come in pink, red, and white. It needs consistent moisture the first year, but becomes drought-tolerant after. Cut back foliage in late fall.
- Coral Bells (Heuchera spp.): Grown for colorful foliage in shades of purple, lime, and bronze. It tolerates dry shade once established. Remove old leaves in spring. It’s deer-resistant and attracts hummingbirds.
- Hosta (Hosta spp.): The go-to for deep shade. Varieties range from tiny to giant. Slugs can be a problem, but choosing slug-resistant types like ‘June’ or ‘Sum and Substance’ helps. Water during dry spells.
- Japanese Forest Grass (Hakonechloa macra): This ornamental grass thrives in partial shade. Its cascading form adds movement. It needs regular water the first season, then becomes quite tough. Cut back in late winter.
- Bleeding Heart (Lamprocapnos spectabilis): Old-fashioned and reliable. It blooms in spring, then goes dormant in summer. Plant it where later plants can cover the gap. It needs well-drained soil.
Native Perennials For Pollinators
Native plants are naturally low maintenance because they evolved here. They support local bees and butterflies without extra effort.
- Butterfly Weed (Asclepias tuberosa): A milkweed that attracts monarchs. It needs full sun and well-drained soil. Deep taproots make it drought-tolerant. It blooms bright orange in summer.
- Wild Bergamot (Monarda fistulosa): A bee magnet with lavender flowers. It tolerates partial shade and moist soil. Powdery mildew can occur, but good air circulation helps. Cut back after flowering.
- Goldenrod (Solidago spp.): Not the cause of hay fever (that’s ragweed). It blooms late summer to fall. It spreads vigorously, so choose clumping varieties like ‘Fireworks’. It’s a late-season pollinator powerhouse.
- New England Aster (Symphyotrichum novae-angliae): Provides purple blooms in fall. It needs full sun and average soil. Pinch back in June to control height. It self-seeds moderately.
- Pennsylvania Sedge (Carex pensylvanica): A native grass-like plant for dry shade. It forms a soft ground cover. It needs no mowing or fertilizing. It’s excellent for erosion control on slopes.
Ground Covers That Reduce Weeding
Ground covers suppress weeds and fill bare spots. They’re the ultimate low-maintenance solution for large areas.
- Creeping Phlox (Phlox subulata): Blooms in spring with a carpet of color. It thrives in full sun and poor soil. It’s evergreen in mild winters. Trim after flowering to keep it compact.
- Pachysandra (Pachysandra terminalis): The standard for dry shade. It spreads by underground runners. It’s deer-resistant but can be invasive in some areas. Use it under trees where grass won’t grow.
- Lamium (Lamium maculatum): Has variegated leaves and pink or white flowers. It tolerates partial shade and moist soil. It spreads quickly but is easy to pull if it goes too far. Good for slopes.
- Vinca Minor (Vinca minor): Also called periwinkle. It has glossy leaves and blue flowers. It thrives in shade and dry soil. It can be aggressive, so plant where it can roam freely.
- Thyme (Thymus serpyllum): A fragrant ground cover for sunny, well-drained spots. It tolerates foot traffic. It blooms in summer with tiny flowers. It needs little water once established.
Planting Tips For Success
Getting your perennials off to a good start reduces future work. Follow these steps for the best results.
- Prepare the soil: Pennsylvania soil is often heavy clay. Mix in 2-3 inches of compost before planting. This improves drainage and adds nutrients. Avoid sand, which can make clay like concrete.
- Plant at the right depth: Dig a hole twice as wide as the root ball but no deeper. The crown should be at soil level. Planting too deep causes rot. Water thoroughly after planting.
- Water wisely: Water deeply once a week for the first month. After that, most perennials need water only during extended dry spells. Overwatering is more common than underwatering.
- Mulch properly: Apply 2-3 inches of organic mulch like shredded bark or leaves. Keep mulch away from stems to prevent rot. Mulch conserves moisture and suppresses weeds.
- Fertilize sparingly: Most perennials need little fertilizer. A light application of balanced slow-release fertilizer in spring is enough. Too much nitrogen leads to floppy growth and fewer flowers.
- Divide when needed: Some perennials like daylilies and hostas benefit from division every 3-4 years. Do this in early spring or fall. It rejuvenates the plant and gives you more plants.
Common Mistakes To Avoid
Even low-maintenance plants suffer from neglect or overcare. Here are pitfalls to skip.
- Overwatering: Pennsylvania gets plenty of rain. Most perennials prefer dry conditions. Water only when the top inch of soil is dry. Yellow leaves often mean too much water.
- Planting in the wrong light: Check the plant tag. A sun-loving plant in shade will be leggy and bloom poorly. A shade plant in sun will scorch. Match the plant to the site.
- Ignoring deer pressure: Deer love hostas, daylilies, and tulips. If deer are common, choose resistant plants like lavender, salvia, or ferns. Use repellents as a backup.
- Not accounting for spread: Some perennials spread aggressively. Plant them where they have room or use barriers. Avoid planting mint or gooseneck loosestrife in open beds.
- Cutting back too early: Leave seed heads and stems for winter interest and wildlife. Cut back in early spring before new growth starts. This also protects the crown from cold.
- Forgetting about fall cleanup: Remove diseased foliage to prevent overwintering pests. Healthy foliage can stay. A light layer of leaves provides natural mulch.

Design Ideas For Low Maintenance Gardens
Grouping plants by their needs reduces work. Here are simple layouts that look great with little effort.
- Sunny border: Combine black-eyed Susan, coneflower, and sedum. Add Russian sage for height. This mix blooms from summer to frost and needs no staking.
- Shady retreat: Layer hostas in front, astilbe in middle, and ferns in back. Add coral bells for color. This combination thrives in dappled light.
- Pollinator patch: Plant butterfly weed, wild bergamot, and goldenrod. Include New England aster for fall color. This attracts bees, butterflies, and birds.
- Slope stabilizer: Use creeping phlox, vinca minor, and lamium. These spread quickly and hold soil. They need no mowing and little water.
- Foundation planting: Mix evergreen ground covers with sedum and coral bells. Add a few dwarf conifers for winter interest. This looks tidy year-round.
Dealing With Common Pests
Even tough plants have occasional issues. Here’s how to handle them without harsh chemicals.
- Slugs and snails: Hand pick at night. Use beer traps or diatomaceous earth. Encourage birds and frogs. Choose slug-resistant hosta varieties.
- Deer: Use fencing or repellents. Plant deer-resistant species like lavender, salvia, and yarrow. Motion-activated sprinklers work well.
- Aphids: Blast off with water. Introduce ladybugs. Use insecticidal soap if severe. They rarely kill healthy plants.
- Powdery mildew: Improve air circulation. Water at soil level. Choose resistant varieties. Remove affected leaves.
- Japanese beetles: Hand pick in morning. Use traps away from garden. Milky spore treatment helps long-term. They prefer certain plants like roses.
