Sunny spots are great for most plants but they can also be the hardest areas to keep tidy. When I first started gardening in my backyard, I struggled to keep weeds under control in the full-sun beds along my driveway. The soil dried out fast, weeds grew even faster, and anything delicate fried by midsummer.
What finally solved the problem was switching to full sun, low-maintenance ground cover plants varieties that can handle heat, poor soil, and long hours of direct sunlight without constant watering or fussing.
These plants thrive in tough conditions, suppress weeds, and create a living carpet that stays attractive without much care.
Why Full-Sun Ground Covers Work
From hands-on experience, full-sun ground covers succeed because:
- They shade the soil, keeping moisture in and weeds out
- Many have deep or drought-tolerant root systems
- They form dense mats that fill gaps quickly
- They tolerate heat, rocky soil, and reflected sun from driveways or patios
- Once established, they can go days or even weeks without watering
They’re ideal for slopes, borders, hot foundations, and anywhere you want color and coverage without work.
What You’ll Actually Need
Most full-sun ground covers are low-fuss. For planting, gather:
- Shovel or trowel
- Compost (to give plants a strong start)
- Mulch (1–2 inches until plants fill in)
- Hose or watering can
- Gloves
- Optional: edging to keep faster spreaders contained
Budget alternatives:
- Use homemade compost
- Mulch using shredded leaves or grass clippings
Best Low-Maintenance Ground Cover Plants for Full Sun
Below are the most reliable full-sun ground covers I’ve grown personally and repeatedly recommend for tough, dry, or hot areas.
1. Creeping Thyme (Thymus serpyllum)
Best for: Dry, sandy, or rocky soil Maintenance: Extremely low
Why it works: Creeping thyme forms a tight, fragrant carpet that smothers weeds. In my front walkway, it’s the only plant that survived full sun plus reflected heat from the pavement.
Benefits:
- Drought tolerant
- Pollinator friendly
- Soft underfoot
- Purple flowers in summer
Important: Needs excellent drainage.
2. Sedum (Stonecrop)
Best for: Dry, poor soil or rock gardens Maintenance: Minimal thrives on neglect
Why it works: Sedum is practically bulletproof. It kept growing even during a 6‑week drought in my zone 7 garden with zero watering.
Benefits:
- Handles heat extremely well
- Evergreen or semi-evergreen in many climates
- Spreads to fill gaps without being invasive
Great options: ‘Angelina’, ‘Dragon’s Blood’, ‘Blue Spruce’
3. Creeping Phlox (Phlox subulata)
Best for: Sunny slopes Maintenance: Low
Why it works: This plant creates a dense mat of evergreen foliage and a stunning carpet of spring flowers. I use it to control erosion on a sunny hill where nothing else stayed put.
Benefits:
- Spring bloom carpet
- Tough, winter-hardy
- Fast coverage
Needs: Slightly acidic, well-drained soil.
4. Lamb’s Ear (Stachys byzantina)
Best for: Hot, dry areas Maintenance: Very low
Why it works: The thick, silvery leaves reflect sunlight and retain moisture. In my garden, it’s one of the few plants that stays good-looking through midsummer heat.
Benefits:
- Soft, child-friendly texture
- Rabbit and deer resistant
- Forms dense clumps
Great for edging sunny beds.
5. Dwarf Mondo Grass (Sun-Tolerant Varieties)
Best for: Pathway edges, borders Maintenance: Very low once established
Why it works: Although often considered a shade plant, dwarf mondo tolerates more sun than people expect especially in moist but well-drained soil.
Benefits:
- Evergreen
- Neat and tidy appearance
- Slowly forms weed-blocking carpets
Works especially well in warm zones (7–10).
6. Portulaca (Moss Rose)
Best for: Very dry, hot areas Maintenance: Very low
Why it works: This succulent annual reseeds lightly and fills sunny beds beautifully. I use it in neglected corners because it thrives where watering is inconsistent.
Benefits:
- Heat-loving succulent foliage
- Blooms nonstop in summer
- Handles extreme drought
Perfect for gravelly or sandy soils.
7. Ice Plant (Delosperma)
Best for: Intense sun, hot driveways Maintenance: Low
Why it works: Ice plant stores water in its leaves, allowing it to stay green and bloom through the hottest part of the season.
Benefits:
- Brilliant summer flowers
- Evergreen in mild climates
- Spreads gently, not aggressively
Needs sharp drainage to avoid rot.
Step-by-Step Planting Instructions
Before started planting you need clear instructions so we give you the instructions which are given below :
1. Prep the Soil
- Loosen the top 4–6 inches.
- Mix in compost for initial boosting.
- Ensure good drainage (critical for thyme, sedum, ice plant).
2. Plant at the Right Time
Best seasons:
- Early spring
- Early fall
Avoid planting during heatwaves.
3. Space Correctly
General spacing:
- Fast spreaders: 12–18 inches
- Slow growers: 8–12 inches
Closer spacing = quicker weed suppression.
4. Water to Establish, Then Reduce
For the first 3–6 weeks:
- Water every 2–3 days Once established:
- Most sun-loving ground covers require very little irrigation
5. Add Light Mulch Until Plants Spread
Mulch around (not over) plants to keep weeds down early.
Professional Tips & Best Practices
- Choose plants based on your soil type full-sun doesn’t always mean drought-tolerant.
- Avoid overwatering sun-loving ground covers often rot in wet soil.
- Re-edge your beds to prevent creeping grass from invading.
- Don’t fertilize sedum or thyme too much nutrient causes floppiness.
- Combine textures (succulents + herbs) for fuller coverage.
Common Beginner Mistakes
- Planting sun-loving ground covers in clay or poorly drained soil
- Overwatering drought-tolerant species
- Planting too far apart
- Expecting coverage in one season most need a year to fill
- Using landscape fabric (roots tangle into it)
FAQ
What is the lowest maintenance ground cover for full sun? Sedum and creeping thyme are the most reliable and need almost no care once established.
What can I plant instead of grass in full sun? Creeping thyme, mondo grass, sedum, or ice plant work well depending on your climate and soil.
What ground cover survives extreme heat? Portulaca, sedum, and ice plant are top performers in hot, dry climates.
Can full-sun ground covers stop weeds? Yes once dense, they block light and prevent weed germination.
How long do they take to fill in? Most ground covers fill in within one growing season with proper spacing and watering.
When NOT to Use Full-Sun Ground Covers
Avoid them if:
- Soil stays waterlogged
- You have heavy clay
- Area receives reflected heat that exceeds the plant’s tolerance
- You need foot traffic tolerance (use thyme or mondo grass instead)
Alternative Options
If ground covers aren’t ideal, consider:
- Gravel mulch + tough perennials
- Xeriscape plantings using drought-tolerant shrubs
- Native prairie-style grasses
Conclusion
Choosing the right ground cover plants for full sun, low maintenance can transform a hot, dry, weed-prone area into an attractive, easy-care garden zone. Sedum, creeping thyme, creeping phlox, lamb’s ear, and other sun-loving ground covers offer long-lasting coverage with almost no upkeep once established.
Prep the soil well, water consistently for the first few weeks, and let these tough plants take it from there. By next season, you’ll have a dense, weed-resistant carpet that thrives in sun and heat with minimal attention.
