Ground Covers That Thrive in Full Sun Without Constant Watering

Why Full-Sun Ground Covers Are a Smart Choice

Ground covers suited for full sun provide more than just aesthetic appeal. They reduce soil erosion, help retain moisture, and keep weeds at bay by forming dense mats of foliage. These sun-hardy plants can also handle heat stress, making them ideal for urban gardens, open fields, and slopes where grass might struggle. Their ability to survive with minimal water makes them an eco-conscious choice, especially in areas prone to drought.

Choosing the right plants means your garden will remain lush and vibrant with little intervention, allowing you to spend more time enjoying your outdoor spaces and less time tending to thirsty plants.

Creeping Thyme: Fragrance and Function

Creeping Thyme (Thymus serpyllum) is a sun-loving superstar, prized for its aromatic foliage and low-growing, mat-forming habit. Once established, it’s remarkably drought-tolerant, requiring little more than occasional watering during prolonged dry spells. In summer, tiny pink to purple flowers blanket the foliage, attracting bees and butterflies while adding a splash of color. Its durability makes it perfect for pathways, rock gardens, and sunny slopes, and it thrives in poor soils where other plants may falter.

Sedum: Succulent Beauty

Sedum, or stonecrop, is one of the most adaptable and resilient ground covers for sunny, dry areas. With its fleshy, water-storing leaves, Sedum can survive weeks without rain, making it a true drought champion. Varieties like Sedum acre and Sedum spurium offer a range of colors and textures, from fine needle-like foliage to broad, flat leaves. In late summer, clusters of star-shaped flowers appear in hues of yellow, pink, or white, creating a vibrant contrast against the succulent foliage. Sedum is ideal for rockeries, container edges, and open beds where heat is intense.

Lantana: Vivid Color and Drought Resistance

Lantana is a heat-loving, flowering ground cover that thrives in the hottest, driest parts of the garden. Its clusters of brightly colored blooms—often in combinations of red, orange, yellow, and purple—add a tropical flair to sunny spaces. Beyond its beauty, Lantana is incredibly tough, tolerating poor soils and extended dry periods once established. It also attracts pollinators like butterflies and hummingbirds, adding life and movement to your garden. In frost-free climates, it can be evergreen, while in colder regions, it returns reliably each spring.

Ice Plant: Jewel-Toned Blooms

The Ice Plant (Delosperma cooperi) is a showstopper for full-sun gardens, producing masses of daisy-like flowers in jewel tones from late spring through summer. Its succulent leaves store water, making it highly drought-tolerant. Ice Plant is particularly effective for erosion control on slopes and in rock gardens, where its vibrant blooms create a striking display against the greenery. It’s a low-maintenance choice that thrives in sandy or well-drained soils and requires minimal care once established.

Creeping Jenny: Golden Ground Hugger

While Creeping Jenny (Lysimachia nummularia) is often associated with moist conditions, its golden-leaved variety, ‘Aurea,’ can handle full sun and dry spells surprisingly well when planted in well-draining soil. Its trailing stems form a dense mat of foliage that turns an even deeper gold in bright sunlight. Creeping Jenny can be used to cascade over walls, fill gaps between pavers, or brighten borders, offering year-round interest with minimal water needs once mature.

Gazania: Sunshine in Flower Form

Gazania, also known as treasure flower, is a bold and cheerful ground cover for hot, sunny spots. Its large, daisy-like flowers open in the sunlight, revealing vivid shades of yellow, orange, pink, and red. Gazania’s silvery-green foliage reflects heat, helping the plant conserve water. It performs well in poor soils and requires little maintenance, making it an excellent choice for adding instant color to arid landscapes.

Dymondia: Tough and Low-Growing

Dymondia margaretae, sometimes called silver carpet, is a resilient ground cover with silvery-green leaves that form a dense, low mat. In summer, it produces small yellow flowers, but its primary appeal lies in its ability to withstand intense sun, drought, and even foot traffic. Dymondia is perfect for filling spaces between stepping stones or covering large sunny areas where grass would struggle. Its reflective foliage helps keep surrounding areas cooler while reducing evaporation.

Blanket Flower: Long-Blooming Beauty

Blanket Flower (Gaillardia) is a native wildflower that doubles as an excellent ground cover for sunny, dry areas. Its warm-toned blooms in red, orange, and yellow last from early summer through fall, providing months of color. Blanket Flower thrives in poor, sandy soils and requires minimal water once established. Its drought tolerance and extended bloom season make it an excellent choice for creating a pollinator-friendly ground cover in full-sun gardens.

Tips for Establishing Full-Sun, Low-Water Ground Covers

Even drought-tolerant plants need a little extra care when first planted. Water regularly during the establishment period to encourage deep root growth, then gradually reduce watering to train the plants to be more self-sufficient. Using mulch around new plantings can help conserve moisture and protect roots from heat stress. Once mature, these ground covers will thrive on natural rainfall or occasional supplemental watering, making them ideal for low-maintenance landscapes.

Designing with Sun-Loving Ground Covers

When designing with drought-tolerant ground covers, think about how foliage colors, flower shapes, and textures can complement each other. Pair the golden tones of Creeping Jenny with the purple blooms of Creeping Thyme, or contrast the silvery foliage of Dymondia with the vibrant flowers of Lantana. Plant in drifts for maximum visual impact, and consider placing more colorful varieties near pathways or entrances where they can be appreciated up close.

Sustainable Beauty for Sunny Spaces

By choosing ground covers that thrive in full sun without constant watering, you not only create a beautiful, low-maintenance landscape but also contribute to water conservation. These plants embrace the challenges of sunny, dry conditions and turn them into opportunities for bold, vibrant garden design. With thoughtful selection and care, your full-sun spaces can become thriving, sustainable showcases of nature’s resilience.
