12 Best Ground Cover Plants to Smother Weeds and Fill Space
The best ground cover plants for sun, shade, and dry spots — low, spreading plants that smother weeds, stop erosion, and fill bare ground beautifully.
12 Best Ground Cover Plants to Smother Weeds and Fill Space
Bare soil is a problem waiting to happen. Every patch of open ground in a garden is an invitation to weeds, an opportunity for erosion, and a surface that loses moisture fast. The natural solution isn’t gravel or bark forever — it’s a living carpet of ground cover plants.
A good ground cover knits across the soil, blocks light from weed seeds, holds moisture, prevents erosion, and turns an awkward bare strip into a feature. Here are 12 of the best, sorted by where they grow.
What Ground Cover Plants Do
- Smother weeds — dense cover blocks the light weed seeds need, dramatically cutting weeding.
- Hold moisture — they shade the soil, reducing evaporation.
- Prevent erosion — roots bind soil on slopes and banks.
- Fill difficult spots — dry shade, slopes, gaps between paving — where little else thrives.
- Cut maintenance — established ground cover is one of the lowest-effort plantings there is.
- Look good — far more alive and attractive than bare earth or endless mulch.

Best Ground Cover for Sun
Creeping Thyme
A fragrant, low, flowering carpet that’s tough enough to walk on — perfect for gaps between paving and stepping stones, where every step releases its scent. It loves hot, dry, sunny spots and feeds bees when it flowers.
Sedum
Carpeting sedums are succulent ground covers that store their own water — ideal for hot, dry banks, gravel gardens, and poor soil where little else will knit together. Many flower and colour up in autumn.
Hardy Geranium
Several hardy geraniums spread into weed-smothering mounds that flower for months. Tough, generous, and easy — a ground cover that genuinely earns its place with colour.
Lamb’s Ear
Soft, silver, fuzzy foliage that spreads into a drought-proof carpet, lighting up sunny beds and edges with cool colour.
Best Ground Cover for Shade
Vinca (Periwinkle)
A reliable evergreen that trails and roots as it goes, smothering weeds even on shady slopes and banks, with pretty blue or white flowers. Vigorous — give it room.
Ajuga (Bugleweed)
Forms a low mat of glossy, often purple or bronze foliage, topped with spikes of blue flowers in spring. Excellent for part shade and the front of borders.
Lamium (Dead-nettle)
One of the best plants for dry shade — its silver-marked leaves brighten gloomy spots under trees and shrubs, and it spreads steadily where many plants fail.
Pachysandra
The classic evergreen ground cover for full shade — a neat, uniform green carpet under trees and along shady foundations where grass won’t grow.
Epimedium
An elegant, tough ground cover for dry shade — wiry stems, dainty spring flowers, and handsome foliage, coping where tree roots steal the water.
Best Ground Cover for Edges and Special Spots
Heuchera
Grown as colourful clumping ground cover for part shade — masses of foliage in lime, caramel, purple, and silver, holding colour year-round.
Creeping Jenny
A golden, trailing carpet for damp ground and bed edges, also brilliant spilling from containers. Bright and cheerful in sun or part shade.
Bergenia (“Elephant’s Ears”)
Big, bold, leathery evergreen leaves that spread into a tough, weed-proof edging, with pink flowers in spring. Unfussy about sun or shade.
How to Plant Ground Cover Successfully
- Clear weeds thoroughly first. This is essential. Ground cover smothers future weed seedlings — it cannot beat established perennial weeds already in the soil. Remove every weed root before planting.
- Improve the soil with compost so plants establish and spread fast.
- Space for spreading. Plant in a staggered grid at the spacing recommended for the plant — closer for faster cover, wider to save money (with a longer wait).
- Mulch between young plants to suppress weeds while the ground cover fills in.
- Water through the first season — ground cover only suppresses weeds once it has knitted together, so help it establish fast.
- Choose vigour to match the spot. A vigorous spreader (vinca, ajuga) is perfect for a big bank but a nuisance in a small mixed border. Match the plant’s energy to the space — and keep enthusiastic spreaders away from delicate neighbours.
A Word of Caution on “Vigorous”
A ground cover plant’s whole purpose is to spread — but the most vigorous ones don’t know where to stop. Plants sold as ground cover can become a problem if planted in the wrong place. Use the strong spreaders for large, contained areas (banks, big shady beds bounded by paving or lawn) and choose gentler, clumping options (heuchera, bergenia) near precious plants. Always check how vigorous a plant is for your region before planting.
Frequently Asked Questions
What is the best ground cover to stop weeds?
Dense, fast-knitting plants like vinca, ajuga, creeping thyme, and pachysandra are the best weed-smotherers. But they only block new weeds — you must clear existing weeds before planting.
What ground cover grows in dry shade?
Lamium (dead-nettle) and epimedium are the best for dry shade — both cope under trees where tree roots take the water and most plants fail.
Can you walk on ground cover plants?
Creeping thyme is the best walkable ground cover — tough enough for paving gaps and light foot traffic, and fragrant underfoot. Most other ground covers don’t tolerate being walked on.
How long does ground cover take to fill in?
Usually one to three seasons, depending on the plant’s vigour and spacing. Closer planting and good soil speed it up; mulch between plants while they knit together.
Will ground cover plants take over my garden?
The most vigorous ones can spread beyond where you want them. Use strong spreaders only in large, contained areas, choose gentler clumping types near delicate plants, and check a plant’s vigour for your region before buying.
