Low-growing ground covers for between patio pavers

The narrow spaces between patio pavers can be difficult to landscape. Bare soil collects weeds, loose gravel shifts underfoot, and traditional lawn rarely receives enough room, sunlight, or moisture to stay healthy. A living ground cover creates a softer, more finished look while helping the hardscape feel integrated with the surrounding garden.

The best plants for paver joints stay short, tolerate occasional foot traffic, and spread without swallowing the entire patio. They also need to cope with heat reflected from stone, irregular watering, and the fast drainage found in shallow gaps. Choosing a plant suited to the conditions is more important than choosing the fastest spreader.

Ground covers can complement a larger outdoor design scheme, from a simple seating area to a fully furnished courtyard. For additional inspiration on practical residential spaces, explore these home design ideas before selecting colors, textures, and planting companions.

What makes a ground cover suitable for paver joints

A strong paving-gap plant should remain low enough that it does not create a tripping edge or hide the surface of the pavers. Most suitable varieties grow between 2 and 6 inches tall, although some may flower slightly higher during the growing season. A compact habit also keeps the patio looking intentional rather than overgrown.

Root behavior matters just as much as height. Choose plants that spread gradually through shallow roots instead of aggressive runners that can lift edging or invade nearby planting beds. It is also useful to select varieties that can handle being trimmed at the patio boundary.

Sun exposure, drainage, and climate will determine which species perform best. South-facing pavers may create hot, dry conditions, while a shaded walkway can stay damp after rain. Observe the area for a few days, noting direct sun, runoff, and how quickly the joints dry before buying plants.

Creeping thyme for sunny, dry patios

Creeping thyme is one of the most reliable choices for sunny spaces between paving stones. It forms a dense, low mat of tiny leaves and produces small pink, purple, or white flowers in summer. Once established, it handles heat and drought well, making it especially useful around brick patios, concrete pavers, and stone pathways.

This aromatic herb generally reaches about 2 to 4 inches tall and releases a pleasant scent when brushed or stepped on lightly. It is suitable for areas with occasional foot traffic, although repeated walking will create thin patches. Full sun and sharply drained soil help prevent the crown from becoming wet and weak.

Plant creeping thyme in small plugs spaced roughly 6 to 12 inches apart, depending on how quickly coverage is needed. Avoid packing rich compost into narrow joints, since excessive moisture can encourage soft growth. A gritty soil blend that sits just below the paver surface gives the roots room without creating a raised planting strip.

Irish moss for a soft, green finish

Irish moss, often sold as Sagina subulata, creates a cushion-like carpet that resembles moss but is technically a low-growing flowering plant. Its bright green foliage and tiny white flowers give patios a fresh, delicate appearance. It works particularly well with pale stone, traditional brick, and cottage-style landscaping.

Unlike creeping thyme, Irish moss prefers consistent moisture and partial sun, especially in warmer regions. It can tolerate some morning or filtered sunlight but may scorch in intense afternoon heat. The planting area should drain well while retaining enough moisture to prevent the foliage from drying out between waterings.

This ground cover is best for lightly used paths rather than the main route to a back door. Place stepping stones or leave a wider paver surface where regular traffic is expected. In damp, shaded joints, check periodically for slugs and remove fallen leaves so the low foliage receives air circulation.

Blue star creeper for adaptable coverage

Blue star creeper, also known as Isotoma fluviatilis, spreads into a dense green mat with small blue or lavender flowers. It is a versatile choice for homeowners who want a softer alternative to gravel but need something that can tolerate occasional foot traffic. Its tiny leaves maintain a neat scale beside narrow rectangular or square pavers.

The plant performs well in sun or partial shade, though it may flower more heavily with several hours of light. It prefers evenly moist soil during establishment and can cope with short dry periods once rooted. Good drainage remains essential, particularly in compacted joints where water may sit after storms.

Blue star creeper can spread quickly under favorable conditions, so define its boundaries near lawns, borders, and drainage channels. Trim the edges several times a year if necessary. Its flexible stems generally recover from light stepping, making it one of the more forgiving choices for a family patio.

Woolly thyme for texture and resilience

Woolly thyme has soft, gray-green foliage and a tightly clustered growth habit. It is valued more for its silvery texture than for abundant flowers, and it pairs beautifully with darker slate, warm terracotta, and weathered concrete. The foliage stays extremely low, often close to 1 or 2 inches tall.

This variety favors full sun, lean soil, and excellent drainage. It is particularly suitable for hot, exposed patios where moisture-loving plants would struggle. The leaves can tolerate occasional contact, but the plant should not be used in a passageway that receives constant foot traffic.

Woolly thyme needs patience during its first season. Water newly planted plugs regularly enough to support root development, then gradually reduce irrigation as they establish. Avoid frequent light trimming while the plants are spreading, since premature cutting can slow coverage. Once mature, remove dead stems and clip back any areas that begin to creep over the pavers.

Brass buttons for a distinctive alternative

Brass buttons, or Leptinella, offers fern-like foliage and tiny yellow button flowers. Depending on the cultivar, its leaves may be green, bronze, or dark purple, giving a paved courtyard more visual contrast than a standard green ground cover. It is especially effective in modern gardens where subtle foliage color is part of the design.

The plant prefers moist, well-drained soil and usually performs best in partial sun or mild full sun. In very hot climates, afternoon shade can protect it from browning. It is more tolerant of light foot traffic than its delicate appearance suggests, but compacted soil and prolonged drought can cause bare spots.

Because brass buttons spreads by short runners, it can fill narrow joints relatively quickly. Keep it away from cracks that lead directly into lawns unless regular edging is acceptable. Use it where a slightly softer, more natural appearance is welcome rather than in a highly formal patio that requires perfectly restrained lines.

Comparing the best options

The right selection depends on the balance between sunlight, moisture, appearance, and use. A dry, exposed patio will usually favor one of the thyme varieties, while a shaded courtyard with irrigation may support Irish moss or brass buttons. Blue star creeper occupies the middle ground and can adapt to several residential settings.

Ground cover	Mature height	Best conditions	Traffic tolerance	Main advantage
Creeping thyme	2–4 inches	Full sun, dry soil	Light	Fragrant foliage and flowers
Irish moss	1–2 inches	Partial shade, even moisture	Light	Soft, bright green carpet
Blue star creeper	2–4 inches	Sun to partial shade	Light to moderate	Adaptable and floriferous
Woolly thyme	1–2 inches	Full sun, very good drainage	Light	Drought tolerance and texture
Brass buttons	1–3 inches	Partial sun, moist soil	Light to moderate	Interesting foliage color

Do not judge a plant solely by its advertised tolerance. Even a traffic-friendly ground cover will fail if the joints are too shallow, the pavers move, or people walk over the same stems every day. In high-use areas, combine living plants with wider paver surfaces or designate a clear route through the patio.

Preparing joints before planting

Successful planting begins with stable, clean pavers. Repair rocking stones and correct drainage problems before adding plants. If water pools in the joints, the issue may be a compacted base or incorrect slope rather than a lack of irrigation. Ground cover cannot compensate for structural problems beneath the patio.

Remove weeds and as many perennial roots as possible, then loosen the upper inch or two of joint material. Use a narrow hand tool to avoid disturbing the paver edges. Fill the space with a free-draining planting mix, leaving it slightly below the top surface so soil and foliage do not spill across the walking area.

Set plugs firmly into the joints and water them immediately. During the first several weeks, check moisture with a finger rather than relying on a fixed schedule. Once roots reach the surrounding soil, reduce watering for drought-tolerant thyme and maintain more regular moisture for Irish moss or brass buttons.

Planting and maintenance essentials

A little preparation and seasonal care will help the ground cover knit together without turning the patio into a high-maintenance garden.

• Select plugs or small nursery plants instead of scattering seed into compacted joints.
• Match the species to the amount of sun, drainage, and summer moisture available.
• Keep new plants slightly below the paver surface to preserve a safe walking line.
• Hand-pull weeds before they mature and reseed among the ground cover.
• Trim spreading edges and replace thin patches at the beginning of the growing season.

Fertilizer is rarely necessary once the plants are established, and heavy feeding can produce soft growth that is less durable. Sweep leaves and debris away regularly, particularly from shaded patios. A light seasonal cleanup is usually enough to maintain a neat appearance while protecting beneficial foliage.

Designing a cohesive patio planting scheme

Ground cover looks most attractive when it relates to other materials in the outdoor room. Match flowering colors with cushions, planters, or nearby perennials, or use silvery woolly thyme to echo pale gravel and galvanized metal. The small scale of these plants also makes them useful around benches, fire pits, and gazebo entrances.

Consider using one primary species throughout the paver joints rather than mixing many varieties in a small area. A single carpet creates visual continuity and makes maintenance easier. Contrast can come from larger containers, ornamental grasses, or a border planting beyond the paving.

Before planting, test a few varieties in separate sections if the patio has noticeably different conditions. A sample area will reveal how quickly each plant spreads, whether the color suits the pavers, and how much watering it requires. This small trial can prevent the expense and disruption of replacing an unsuitable ground cover later.

Transforming empty paver joints into a living surface can make a patio feel cooler, softer, and more connected to the landscape. Choose the plant that matches your light and moisture conditions, prepare the gaps carefully, and install a few starter plugs this season to begin building a durable green carpet.
