Ground Cover Plants – Choose the Right One by Condition

Ground cover plants are the low, spreading plants you use to carpet bare ground instead of fighting it with mulch and a weed-pulling routine every spring. They are the answer to the problem spots every yard has: the dry strip along the driveway where grass scorches, the shady patch under a maple where nothing takes, the slope you hate to mow, the gaps between stepping stones that fill with weeds. Pick the right one for the conditions you actually have, and within two or three seasons you get a living mat that smothers weeds, holds soil in place, and looks far better than the dirt it replaced.

The catch is that “the right one” depends entirely on the spot. A groundcover that thrives in baking full sun will rot in wet shade, and a few of the toughest, most heavily marketed spreaders will swallow your whole garden and your neighbor’s if you let them. So this is a choose-by-condition guide, not just a list. Below you will find what groundcovers do and why they are worth planting, then curated picks organized by the situation you are trying to solve, followed by how to plant and care for an area, and an honest warning about the aggressive choices to avoid or contain.

Why plant a groundcover instead of mulch or grass

A groundcover earns its keep by doing several jobs at once, which is why a single well-chosen planting can replace mulch, reduce mowing, and solve a chronic problem area in one move.

• It suppresses weeds. A dense mat shades the soil so weed seeds never get the light they need to germinate, and its roots claim the water and nutrients weeds would otherwise grab. This is “living mulch”: once it knits together, you stop hauling bark chips every year because the plant covers the ground for you.
• It retains moisture and cools the soil. Bare ground bakes and dries. A leafy carpet shades the surface, slows evaporation, and keeps the root zone of nearby shrubs and perennials cooler and more even.
• It holds slopes and stops erosion. On a hillside, fibrous and spreading roots knit the soil together and the foliage breaks the force of rain before it can wash soil downhill. This is the classic fix for a bank that is too steep to mow safely.
• It grows where grass and most plants fail. Deep dry shade under trees, hot sun-baked strips, sandy or poor soil, the cracks between pavers, the awkward sliver beside the garage: these are the spots turfgrass gives up on, and groundcovers are bred for exactly them.
• It softens hardscape and replaces lawn. Tucked between steppingstones or pavers, low spreaders soften hard edges and fragrant ones reward you when you brush them. Mass-planted, several of these make a genuine no-mow lawn alternative that supports pollinators in a way turf never will.

The trade-off is patience. Groundcovers follow the old nursery rule of “sleep, creep, leap”: they barely move year one, stretch year two, and close ranks year three. Plant for the spot, space correctly, and that wait pays off for a decade or more.

Best groundcovers for full sun and dry spots

These are the plants for the hot, exposed, low-water places: south-facing beds, sun-baked slopes, gravelly strips, and anywhere the soil drains fast and the irrigation rarely reaches. They want drainage above all else and will rot in soggy ground.

• Creeping thyme (Thymus serpyllum), zones 4-9. Evergreen, 2 to 4 inches tall, drought and salt resistant. A fragrant low mat that explodes into pink, purple, or white pollinator-friendly bloom in summer and tolerates light foot traffic. The all-rounder for sunny, dry, poor soil; feed it too richly and it gets leggy.
• Sedum / stonecrop (Sedum spp.), zones 3-10. The toughest pick for hot, dry slopes where nothing else survives. Low mat-forming types store water in fleshy leaves, shrug off drought, and pull in bees. Spreads reliably, asks for almost nothing but sun and drainage. Choices like ‘John Creech’ stay only a couple of inches tall.
• Creeping phlox (Phlox subulata), zones 3-9. A dense, mossy, evergreen carpet that disappears under a solid sheet of pink, lavender-blue, or white flowers in spring. Excellent tumbling over walls and on sunny banks for erosion control; drought tolerant once established. Shear lightly after bloom to keep it tight.
• Ice plant (Delosperma), zones 6-10 depending on type. A succulent for the driest, hottest, best-drained spots, with jewel-toned daisy-like flowers that bloom for weeks and draw butterflies. Needs sharp drainage and full sun; superb in xeriscapes and rock gardens.
• Prostrate junipers (Juniperus horizontalis), zones 3-9. A tough evergreen shrub used as groundcover. ‘Blue Rug’ hugs the ground at 4 to 6 inches and a single plant can eventually spread to 8 feet, with silver-blue needles that take on purple winter tones. The go-to for large dry banks and slope stabilization, and far longer-lived than the herbaceous options.

Two more worth knowing for sun: hens-and-chicks (Sempervivum) for tucking into hot cracks where nothing else will root, and blue fescue or other ornamental grasses for texture in dry, exposed beds.

Best groundcovers for shade and under trees

Dry shade under established trees is the hardest spot in most yards because the tree wins every contest for water and the canopy blocks light. These plants are built for cool, low-light, often root-filled ground. Water them well the first year so they can compete.

• Pachysandra (Pachysandra terminalis), zones 4-8. Glossy evergreen rosettes, about 6 to 8 inches tall, that form a uniform carpet even in dry shade under trees where almost nothing else covers. It is the default for a reason, but note the warning later: it spreads aggressively and a native alternative is often the better choice.
• Ajuga / bugleweed (Ajuga reptans), zones 3-9. A glossy, low (2 to 3 inches) spreader that throws up cobalt-blue flower spikes bees love, and thrives in full shade where most groundcovers sulk. Varieties like ‘Chocolate Chip’ and ‘Black Scallop’ add deep purple foliage. A fast, runner-spreading member of the mint family, so site it where spread is welcome or edge it in.
• Sweet woodruff (Galium odoratum), zones 4-8. Bright green whorled foliage topped with delicate white spring flowers and a hay-sweet scent. Fast to fill cool, moist shade and excellent under trees and along shady paths. Can be vigorous in ideal conditions; tamer in cold climates where it dies back.
• Foamflower (Tiarella cordifolia), zones 3-9. A North American native with fluffy white spring flower spikes and handsome semi-evergreen leaves. Clumping and well-mannered rather than a runaway spreader, it is one of the best natives for a woodland shade carpet.
• Ferns, zones vary. Not spreaders in the carpet sense, but planted in drifts, native ferns fill shade beautifully and need essentially no care once established. Mix two or three species for layered texture in deep shade.
• Hostas, zones 3-9. Massed closely, hostas read as a lush groundcover for shade and part shade, smothering weeds under broad overlapping leaves. Choose larger varieties spaced to touch at maturity, and watch for slugs.

For a native shade spreader to use instead of pachysandra or vinca, wild ginger (Asarum canadense) forms colonies of heart-shaped leaves in moist shade and stays in bounds.

Best groundcovers for foot traffic and between pavers

Here you need to be honest about how much walking happens, because “walkable” covers a wide range. Match the plant to the real traffic, give it at least a couple of inches of gap and 6 inches of loose, decent soil between the stones, and it will fill in.

True walkable, takes regular stepping:
– Creeping thyme (Thymus serpyllum), zones 4-9. The best all-around stepable groundcover: low, tough, sun-loving, and it releases a wonderful scent when crushed underfoot. Handles light-to-moderate traffic and bakes happily in the reflected heat off paving.

Occasional stepping, light traffic:
– Corsican mint (Mentha requienii), zones 6-9. Tiny, intensely peppermint-scented leaves form a flat film between stones in part shade with steady moisture. Releases fragrance when stepped on, but it is delicate, so it is for paths you cross rather than pound.
– Blue star creeper (Isotoma fluviatilis), zones 5-9. A tough, fast mat studded with little blue star flowers all summer that tolerates light foot traffic and works as a small-scale no-mow filler in sun to part sun.

Fill the gaps, look only or rare stepping:
– Irish moss (Sagina subulata), zones 4-8. A bright green, moss-like carpet barely 2 inches tall for edging and filling between stones; takes light traffic in cooler, part-shade spots.
– Dwarf mondo grass (Ophiopogon), zones 6-11. Tidy grassy tufts that tolerate more stepping than the delicate options and stay evergreen, good for narrow gaps.

Avoid planting delicate-leaved spreaders where people actually walk; the finer the foliage, the less abuse it takes.

Best groundcovers for slopes and erosion control

A slope adds two demands: the planting has to knit the soil against washout, and you have to be able to plant and establish it on an incline. Deep or fibrous roots and a vigorous spreading habit matter more than flowers here.

• Creeping juniper (Juniperus horizontalis), zones 3-9. The workhorse for steep, dry, sunny banks. Tough evergreen, extreme drought tolerance, and a wide-spreading habit that locks soil in place. Plant on the slope and let it run.
• Cotoneaster (Cotoneaster spp.), zones 4-7 depending on species. Low, arching, woody groundcover types root as they spread and grip a bank firmly, with small flowers followed by red berries. Good for larger slopes that want some structure and four-season interest.
• Bearberry (Arctostaphylos uva-ursi), zones 2-6. A native evergreen that tolerates poor, sandy soil in sun or part shade, forms a thick carpet in two or three seasons, and offers white spring flowers, red berries, and bronze fall color. One of the best natives for erosion control in cold regions.
• Native grasses and sedges. For a naturalistic, low-input slope, regionally native bunch grasses and spreading sedges (Carex) develop deep root systems that hold soil exceptionally well and need no mowing. Choose species native to your area for the toughest, best-behaved result.

Sedum and creeping phlox from the full-sun list also do double duty on sunny slopes, and sweet woodruff will cover a shady bank.

Lawn alternatives you can actually live with

Replacing turf with a groundcover means trading mowing for a different, usually lighter, set of chores. Be realistic: most groundcover “lawns” take some foot traffic but not a backyard football game, and they look more meadow than manicured. You also do not have to convert everything at once; start with one bed and divide plants outward over time.

• Clover (Trifolium repens), zones 3-10. The classic turf alternative. It fixes its own nitrogen, stays green in drought, takes moderate traffic, flowers for pollinators, and mixes happily into thin lawns. Mow occasionally or leave it; either way it asks far less than grass.
• Creeping thyme, zones 4-9. Mass-planted as a no-mow lawn in full sun, it gives you a fragrant, flowering, drought-proof carpet that bees adore. Best for small to mid-size sunny areas with light traffic rather than a whole play yard.
• Native sedges (Carex spp.), zones vary. Several sedges form soft, grass-like, no-mow lawns suited to shade or sun depending on species, including dry-shade workhorses like Pennsylvania sedge. Being native, they support local insects and shrug off the conditions that defeat turf.

Bugleweed, blue star creeper, and mazus also serve as small-scale lawn substitutes in the right light.

How to plant a groundcover area

Good results come from prep and patience, not from cramming plants together. The single most important step is starting weed-free, because once a groundcover knits in, pulling weeds out of it is miserable.

Clear the ground first. Remove all existing grass and weeds before planting. Dig or smother them; if you have time, sheet-mulch by covering the area with cardboard and several inches of mulch for a season, or solarize by wetting the ground and covering it with clear plastic for four to six weeks. Skipping this is the most common reason a groundcover planting fails.

Space for the mature plant, not for instant cover. Resist the urge to pack plants tight. As a rule, set them about as far apart as their expected mature spread; check the plant tag. For reference, plants set 12 inches apart cover roughly 85 square feet, and at 18 inches apart they cover about 200 square feet. Stagger them in zigzag rows so they meet evenly. Dig each hole as deep as the root ball and two to three times as wide, set the plant at the same level it grew in the pot, firm the soil, and water in.

The weed-barrier debate. Skip the woven landscape fabric under a spreading groundcover. Fabric is meant for plantings that stay put, like shrubs in stone mulch; under a groundcover it actively works against you, because runners and rooting stems cannot root down through it, and over a year or two soil and debris collect on top and weeds simply grow in that layer while the fabric chokes the plants you want. Use a biodegradable barrier instead: a layer of cardboard or newspaper under mulch at planting time suppresses weeds while you wait, then breaks down and lets your groundcover root and spread freely.

Mulch the gaps while it fills in. Apply about a 2-inch layer of organic mulch between the young plants to hold moisture and block weeds during the establishment period, keeping it a few inches back from the stems. As the groundcover closes in, it takes over the mulch’s job.

Plan for the wait. Expect two to three growing seasons for full coverage. Water consistently the first year, especially in sun and on slopes, so roots establish before you ease off.

Caring for an established groundcover

Once it has filled in, a well-chosen groundcover is close to self-sufficient, which is the whole point. A little upkeep keeps it dense and in bounds.

• Shear or mow after bloom. Many spreaders (creeping phlox, thyme, sweet woodruff, ajuga, sedum) stay tighter and look fresher if you trim or mow them lightly once flowering finishes, which also discourages bare, weedy centers.
• Patrol the edges. Run a spade or install edging along the borders once or twice a year to stop vigorous types from creeping into lawn, beds, or a neighbor’s yard.
• Patch the gaps. If thin spots appear, divide and replant from the fuller areas rather than buying new; most groundcovers transplant easily and you will close gaps before weeds find them.
• Feed lightly, if at all. Most of these plants prefer lean conditions. Over-fertilizing makes them floppy and leggy; a thin topdressing of compost is plenty for the hungry ones.

The aggressive and invasive groundcovers to avoid or contain

This is where groundcovers earn their bad reputation, and it deserves a frank warning. Several of the fastest, cheapest, most heavily sold “easy” groundcovers are the very ones that escape gardens, smother native plants, and become nearly impossible to remove. Fast spread is exactly what makes a plant useful as a groundcover and exactly what makes it dangerous, so the line between “vigorous” and “invasive” is one you have to watch.

Treat these as plants to skip or strictly contain, especially near woods, water, or open land:

• English ivy (Hedera helix). Listed as a noxious weed in much of the country. It blankets the ground, then climbs and kills trees and walls, and the sap irritates skin. Do not plant it.
• Periwinkle / vinca (Vinca major and Vinca minor). A pretty evergreen with blue spring flowers that re-roots wherever its stems touch soil, forming dense mats that crowd out native wildflowers and escape readily into woodland. Genuinely useful in a contained, edged bed, but a known invader, so contain it deliberately or choose something else.
• Creeping Jenny (Lysimachia nummularia). A fast yellow-leaved spreader that runs out of bounds in moist ground and is listed as noxious across much of the Northeast. Keep it strictly to containers, where it behaves.
• Lily of the valley (Convallaria majalis). Fragrant and beloved, but it spreads by aggressive underground rhizomes into a monoculture that is very hard to dig out, and every part is poisonous. Plant only where you can confine the roots.
• Pachysandra (Pachysandra terminalis). The classic shade groundcover is also a steady spreader that escapes its bed and forms dense colonies in natural areas. It is not as dangerous as ivy, but if you have a native alternative, take it.

Others to recognize and refuse include bishop’s weed (goutweed), wintercreeper (Euonymus fortunei), yellow archangel, and Japanese honeysuckle, all sold or passed along as groundcovers and all escape artists.

Choose well-behaved natives instead. The good news is that for nearly every aggressive spreader there is a native or well-mannered substitute that does the same job without the regret: foamflower, wild ginger, native ferns, and Pennsylvania sedge for shade in place of pachysandra and vinca; bearberry, native grasses, and creeping junipers for sun and slopes; creeping phlox and sedum for sunny carpets. Natives spread enough to cover ground but rarely enough to take over, they support local pollinators and birds, and they thrive in your conditions without a fight. If you do want a vigorous non-native, contain it from day one with deep edging or a pot, and never let it set seed near wild land.

Pick by your conditions, prep the ground, give it three seasons, and the right groundcover turns your hardest, ugliest spots into the part of the garden you stop worrying about. Start with the one bad spot that bothers you most, match a plant to its light and soil from the lists above, and let it do the work.
