Ground Cover Plants Guide 2026: 25 Best Species for Every Condition
Ground Covers Solve Three Problems at Once
A well-chosen ground cover eliminates lawn maintenance in difficult areas, suppresses weeds by shading the soil surface, and controls erosion on slopes where mowing is dangerous. The right plant at the right spacing forms a living mulch within 1-3 growing seasons — zero mowing, zero weeding (once established), and zero bare soil.
The wrong plant becomes an invasive nightmare that consumes neighboring beds and refuses to leave. English ivy and vinca (periwinkle) are the cautionary tales — popular, attractive, and ecologically destructive in most of North America. This guide focuses on species that cover ground without conquering it.

The "Stepable" Plants — Ground Covers You Can Actually Walk On
Most ground covers tolerate zero foot traffic — one step crushes the foliage and it takes weeks to recover. These species can handle occasional to regular walking:
| Plant | Traffic Tolerance | Notes | |-------|------------------|-------| | Creeping Thyme | Best of all ground covers | Release fragrance when stepped on. Tolerates 1-2 walks/day across the same path. Blooms attract bees — do not plant as a primary walkway near doors. | | Scotch Moss / Irish Moss (Sagina subulata) | Moderate | Needs consistent moisture. Turns brown in hot, dry summers — recovers in fall. Feels like a soft green carpet. | | Dymondia (Dymondia margaretae) | Moderate | Silver-green foliage. Tolerates light foot traffic. Best for Southern California and similar Mediterranean climates. | | Rupturewort (Herniaria glabra) | Good | Tiny green leaves form a dense 2-inch mat. Tolerates regular walking. The most underrated stepable. Turns bronze in winter. | | Blue Star Creeper (Isotoma fluviatilis) | Light to moderate | Tiny blue star-shaped flowers. Spreads quickly (18-24"/year). Can be invasive in moist climates — contain with edging. |
Erosion Control on Slopes
A slope over 10% grade cannot be safely mowed. Ground covers are the permanent solution — their roots hold soil better than grass because they form a dense, fibrous mat rather than individual plants.
Best slope plants by region:
- Northeast/Midwest (Zones 4-7): Creeping juniper (Juniperus horizontalis, ''Blue Rug'' or ''Wiltonii'', 6 inches tall, 6-8 foot spread), creeping phlox, bearberry (Arctostaphylos uva-ursi, native, evergreen, red berries)
- Southeast (Zones 7-9): Mondo grass (Ophiopogon japonicus), Asiatic jasmine (Trachelospermum asiaticum — NOT Confederate jasmine, which is a vine), creeping raspberry (Rubus calycinoides, crinkled green leaves, orange-red fall color)
- West Coast (Zones 8-10): Dymondia, creeping rosemary (Rosmarinus officinalis ''Prostratus''), ceanothus ''Centennial'' (low-growing California lilac)
- Southwest (Zones 5-9): trailing lantana, creeping germander (Teucrium chamaedrys ''Prostratum''), woolly thyme (Thymus pseudolanuginosus)
Planting a slope: Do not till — tilling loosens soil and accelerates erosion. Dig individual planting holes. Install plants in staggered rows (diamond pattern) rather than straight lines — this intercepts water flowing downhill. Water with a soaker hose running horizontally across the slope (not vertically). Cover exposed soil between plants with biodegradable erosion-control blanket (jute or coir mesh) until plants fill in.
Spacing and Coverage Math
The biggest mistake with ground covers: planting too far apart because "they will fill in." Yes, they will — in 3-5 years. During those years, weeds colonize the bare soil and you spend more time weeding than you would have mowing.
Formula for number of plants needed: (Area in square feet) ÷ (Spacing in feet)² × 1.1 (10% extra for fill-in losses)
Example: a 100 sq ft area planted at 12-inch spacing. 100 ÷ 1² × 1.1 = 110 plants.
| Spacing | Plants per 100 sq ft | Time to Full Coverage | |---------|---------------------|----------------------| | 8 inches | 248 | 1-1.5 growing seasons | | 12 inches | 110 | 1.5-2 growing seasons | | 18 inches | 49 | 2-3 growing seasons | | 24 inches | 28 | 3-4 growing seasons |
For the impatient: plant at 8-12 inch spacing even though it costs more upfront. The cost is in labor (weeding bare soil for 3 years) vs. plants (buying more now). The plants are cheaper than your time.
The "Never Plant" List
These ground covers are ecological disasters in large portions of North America. They escape cultivation, invade natural areas, and are nearly impossible to eradicate:
- English Ivy (Hedera helix): Swallows forests. Invasive in 18+ states. If you have it, remove it — but expect a 2-3 year battle.
- Vinca / Periwinkle (Vinca minor, V. major): Smothers forest understory. V. major is worse than V. minor. Both are invasive across the Eastern U.S.
- Japanese Spurge (Pachysandra terminalis): Less aggressive than ivy but still escapes into woodlands. The native alternative: Allegheny spurge (Pachysandra procumbens) — native to the Southeast, slower-growing, more interesting foliage.
- Winter Creeper (Euonymus fortunei): Climbs and kills trees. The variegated varieties at garden centers are the same species and equally invasive once they escape.
- Goutweed / Bishop''s Weed (Aegopodium podagraria): A single root fragment regenerates the entire plant. Once established, it is forever. The variegated form is slightly less aggressive but still invasive.
Key Takeaways
Choose ground covers by condition (sun + moisture + foot traffic), not just by appearance. Space plants at 8-12 inches for coverage in 1-2 seasons. On slopes, plant in staggered rows and use erosion-control blanket on bare soil between plants. Creeping thyme is the best overall stepable ground cover. For dry shade under trees, epimedium and liriope are the most reliable. Never plant English ivy, vinca, or winter creeper — they destroy native ecosystems and cannot be removed once established.
Frequently Asked Questions
What is the fastest-spreading ground cover?
Creeping Jenny (Lysimachia nummularia) spreads 24-36 inches per year in moist soil. It is aggressive but controllable with edging. For dry, sunny conditions: sedum and ice plant spread 18-24 inches per year. For the fastest complete coverage: plant at 8-inch spacing — the density, not the spread rate, is what covers bare soil fastest.
Can I walk on ground cover plants?
Most cannot tolerate regular foot traffic. The exceptions: creeping thyme (light traffic, releases fragrance), rupturewort (good traffic tolerance, the most underrated stepable), and Scotch/Irish moss (moderate traffic but needs consistent moisture). No ground cover handles the daily traffic of a primary walkway — use pavers or gravel for paths and plant ground covers beside them.
How do I kill grass to plant ground cover?
Sheet mulching: cover the grass with a single layer of cardboard (remove tape and staples), overlap edges by 6 inches, wet thoroughly, cover with 3-4 inches of compost or mulch. The cardboard smothers the grass, which decomposes into soil over 2-3 months. Plant ground covers directly through the mulch into the soil beneath. Do NOT use landscape fabric — it prevents ground covers from spreading and eventually becomes exposed as mulch decomposes.
Will ground covers choke out weeds?
Once fully established (complete coverage, roots interlocked), yes — a dense ground cover mat shades the soil surface and prevents 90%+ of weed seed germination. During the establishment period (years 1-2, before full coverage), you must weed between plants. This is the price of admission. After full coverage, maintenance drops to near zero — the occasional dandelion poking through, pulled in seconds.
What ground cover grows under pine trees?
The soil under pines is dry, acidic (pH 4.5-5.5 from decomposing needles), and shaded. Best options: epimedium (tolerates dry shade and acidic soil), liriope (nearly indestructible), sweet woodruff (prefers moist but survives dry), and creeping wintergreen (Gaultheria procumbens, native, evergreen, red berries, minty fragrance — the plant that gave wintergreen its name). Avoid hostas — they struggle in dry shade without supplemental water.
