Top Plants to Use as Gapfillers Between Tiles

When designing patios, walkways, or garden paths, the spaces between tiles often present a challenge. These gaps, if left empty or filled with plain materials like sand or gravel, can look uninspired and miss an opportunity to add character and texture to your outdoor space. One of the most appealing solutions is to use plants as gapfillers between tiles. These plants not only fill the voids but also soften hardscapes, introduce greenery, and can even add fragrance or attract pollinators.

Choosing the right plants for this purpose requires considering factors such as growth habits, tolerance to foot traffic, sunlight exposure, and maintenance needs. In this article, we will explore some of the best plants to use as gapfillers between tiles, helping you transform your tiled areas into verdant, inviting spaces.

Why Use Plants Between Tiles?

Before diving into plant recommendations, it’s important to understand the benefits of using plants between tiles:

• Aesthetic Appeal: Plants break up the monotony of hard surfaces and add color and texture.
• Softening Effect: The greenery softens the harshness of stone or ceramic tiles.
• Environmental Benefits: Plants improve air quality and support biodiversity by attracting bees and butterflies.
• Erosion Control: Plants can help stabilize soil or substrate in tile gaps.
• Cooler Surfaces: Vegetation can reduce heat absorption by hard surfaces.

Characteristics of Ideal Gapfiller Plants

Plants used between tiles should ideally have these qualities:

• Low Growth Habit: They should stay low to avoid becoming a tripping hazard.
• Creeping or Mat-forming: To fill gaps evenly and suppress weed growth.
• Tolerance to Foot Traffic: Some degree of trampling tolerance is important.
• Drought Tolerance: Tiles often receive less water; drought-tolerant species do better.
• Sunlight Adaptability: Choose plants based on the sun exposure of the area (full sun, partial shade).
• Easy Maintenance: Low-maintenance plants are preferable for ease of care.

With these criteria in mind, let’s move on to some top plant choices.

1. Creeping Thyme (Thymus serpyllum)

Overview

Creeping thyme is a classic choice for filling gaps between pavers and tiles. It has a low-growing, mat-forming habit that covers ground effectively without growing tall or lanky.

Features

• Height: 2–3 inches
• Spread: Up to 12 inches or more
• Sun Requirements: Full sun
• Foot Traffic: Moderate tolerance; withstands light walking
• Bloom Time: Late spring to early summer; produces small purple flowers
• Benefits: Fragrant leaves that release a pleasant aroma when stepped on; attracts pollinators like bees; drought-resistant once established

Considerations

Thyme prefers well-drained soil and full sun exposure. It may struggle in heavy shade or overly wet conditions.

2. Irish Moss (Sagina subulata)

Overview

Irish moss is not true moss but a tiny perennial groundcover with bright green cushions of foliage. It creates a soft carpet-like appearance perfect for filling narrow tile gaps.

Features

• Height: 1–3 inches
• Spread: Spreads slowly via rhizomes
• Sun Requirements: Partial shade to full sun
• Foot Traffic: Moderate tolerance; tolerates light walking but not heavy traffic
• Bloom Time: Small white star-shaped flowers in late spring

Considerations

Prefers moist but well-drained soil. It’s ideal for shaded or semi-shaded locations where thyme may not thrive.

3. Blue Star Creeper (Isotoma fluviatilis)

Overview

Blue star creeper is a low-growing perennial with tiny star-shaped blue flowers. It’s an excellent alternative when you want something flowering and dense.

Features

• Height: 1–2 inches
• Spread: Creeping habit that forms dense mats
• Sun Requirements: Full sun to partial shade
• Foot Traffic: Good tolerance; suitable for light to moderate foot traffic
• Bloom Time: Summer; attractive blue flowers

Considerations

It grows well in moist soils and tends to spread quickly once established.

4. Corsican Mint (Mentha requienii)

Overview

Corsican mint is an aromatic groundcover with tiny round leaves that emit a strong mint fragrance when crushed. It’s excellent for sensory gardens or aromatic pathways.

Features

• Height: Very low, less than an inch
• Spread: Forms dense mats
• Sun Requirements: Partial shade preferred
• Foot Traffic: Moderate tolerance; withstands gentle walking but not heavy use
• Bloom Time: Summer; small purple flowers

Considerations

Needs regular watering in dry climates and protection from intense afternoon sun.

5. Dymondia (Dymondia margaretae)

Overview

Known as silver carpet or silver cushion plant, dymondia offers silvery-green foliage that contrasts beautifully with darker paving stones or tiles.

Features

• Height: 1–2 inches
• Spread: Fast spreading groundcover
• Sun Requirements: Full sun to partial shade
• Foot Traffic: High tolerance; handles moderate foot traffic well
• Bloom Time: Yellow daisy-like flowers in summer

Considerations

Excellent drought tolerance makes it ideal for Mediterranean or dry climates.

6. Baby’s Tears (Soleirolia soleirolii)

Overview

Baby’s tears is a delicate-looking plant with tiny rounded leaves that create a lush green carpet between tiles. It’s particularly suited for shaded areas.

Features

• Height: Up to 3 inches
• Spread: Spreads quickly and densely via runners
• Sun Requirements: Shade to partial shade
• Foot Traffic: Low tolerance; best for areas with minimal walking over it

Considerations

Needs consistent moisture and protection from direct sunlight.

7. Moss (Various Species)

Overview

In shady, moist environments where grass struggles, moss can be an excellent natural filler between tiles. Mosses create a soft green cushion that thrives in cool, damp conditions.

Features

• Height: Very low growing (less than an inch)
• Spread: Spreads gradually over time
• Sun Requirements: Shade preferred
• Foot Traffic: Low tolerance; best where foot traffic is minimal

Considerations

Requires moist conditions and acidic soils; may need some effort to establish if moss isn’t native to your region.

8. Ajuga (Ajuga reptans)

Overview

Also known as bugleweed, ajuga is a fast-spreading groundcover with colorful foliage ranging from deep purple to green with bronze hues, often complemented by spikes of blue flowers.

Features

• Height: 4–6 inches (slightly taller than other gapfillers)
• Spread: Spreads quickly via runners
• Sun Requirements: Partial shade to full sun
• Foot Traffic: Moderate tolerance

Considerations

Ajuga can tolerate some foot traffic but may be better suited near edges rather than directly between heavily used tiles due to its slightly taller height.

Tips for Planting Between Tiles

To ensure success when planting gapfillers:

1. Prepare Proper Growing Medium: Use a mixture of quality soil and sand/organic matter suitable for drainage.
2. Ensure Adequate Watering: Newly planted areas need consistent moisture until established.
3. Consider Tile Spacing: Wider joints (at least 1/4 inch) accommodate plants better.
4. Use Edging if Needed: To keep plants contained within tile joints.
5. Regular Maintenance: Trim back overgrown areas and replace any patches that fail.
6. Assess Sun Exposure: Match plant species to the amount of sunlight your tiled area receives.
7. Prevent Weeds: Filling gaps densely suppresses unwanted weeds effectively.

Conclusion

Using plants as gapfillers between tiles is an inspired way to enhance your outdoor living spaces by blending natural beauty with functional design. Depending on your climate, sunlight exposure, foot traffic levels, and aesthetic preferences, you can select from many versatile groundcovers such as creeping thyme, Irish moss, blue star creeper, corsican mint, dymondia, baby’s tears, mosses, or ajuga.

Each plant offers unique features — from fragrant scents and colorful blossoms to silver foliage or lush softness — that can dramatically transform hardscaped areas into vibrant green corridors full of life and charm. By carefully selecting species suited for your environment and maintaining them properly, your tiled spaces will become elegant, eco-friendly retreats enjoyed year-round.

Whether you prefer the aromatic appeal of thyme underfoot or the plush softness of moss in shaded nooks, integrating these gapfiller plants will elevate both the style and function of your outdoor tiled surfaces.
