Full Sun Drought Tolerant Ground Cover Plants
Transform bare, sun-baked soil into a lush, low-maintenance carpet of greenery. Discover the toughest ground covers that thrive in full sun, survive drought, and keep your landscape beautiful with minimal watering.
Explore Top Plant PicksWhy ground covers matter in hot, dry landscapes: A well-chosen full sun drought tolerant ground cover does far more than fill empty space. It cools the soil, suppresses weeds, reduces erosion, and slashes your water bill. The best choices establish quickly, spread steadily, and look good even through the hottest stretches of summer — without constant irrigation or fuss.
Understanding "Full Sun" and "Drought Tolerant"
Before you shop, it helps to understand exactly what these two labels mean, because they are not interchangeable. "Full sun" describes a light requirement: the plant needs at least six hours of direct, unfiltered sunlight each day. Many ground covers that tolerate part shade will sulk, thin out, or refuse to flower in a true full-sun position.
"Drought tolerant" describes a water strategy. These plants have adapted to survive — and often thrive — on rainfall alone once established. They typically feature deep taproots, waxy or fuzzy leaves, or succulent tissues that store moisture. True drought tolerance usually develops after a plant's first full growing season, so even the toughest varieties need regular watering while they settle in.
The sweet spot is a plant that demands both conditions. When you combine full sun exposure with genuine drought tolerance, you get a ground cover that laughs at heat waves, sandy soil, and south-facing slopes. If you want to broaden your palette beyond ground covers, our guide to drought tolerant plants covers shrubs, perennials, and more for water-wise gardens.
Benefits of Low-Water Ground Covers
- Water savings: Established drought-tolerant covers often survive on natural rainfall, cutting irrigation demand dramatically.
- Weed suppression: A dense mat blocks sunlight from weed seeds and crowds out competition.
- Erosion control: Spreading roots hold soil in place on slopes, banks, and bare patches where grass struggles.
- Soil cooling: Living mulch keeps root zones cooler than bare earth or gravel, benefiting nearby plants.
- Low maintenance: Once established, most need little beyond an occasional trim and seasonal cleanup.
- Pollinator support: Many flowering options feed bees and butterflies while shrugging off dry spells.
Top Full Sun Drought Tolerant Ground Cover Plants
The following selections represent a range of growth habits — from ground-hugging mats to flowering creepers — so you can match the right plant to your slope, border, or problem patch. Think of them in terms of establishment ease and value tier rather than any specific price point.
Creeping Thyme
A fragrant, foot-traffic-tolerant mat that thrives in poor, rocky soil. Tiny pink or purple flowers appear in early summer. Ideal between stepping stones and along path edges.
Sedum (Stonecrop)
Succulent leaves store water, making sedum one of the most bulletproof full-sun covers. Low-growing types form dense carpets and tolerate sandy or gravelly ground with ease.
Ice Plant
Glittering, fleshy leaves and vivid daisy-like blooms create a carpet of color in hot, dry spots. Excellent on slopes and coastal gardens where drainage is sharp.
Lantana
A fast-spreading shrubby cover with multi-colored flower clusters that butterflies adore. Extremely heat and drought tolerant; trim lightly to keep it dense.
Creeping Juniper
An evergreen conifer that forms a weed-proof carpet of blue-green foliage. Superb on banks and in hot, exposed sites; nearly maintenance-free once rooted.
Blue Fescue
A clumping ornamental grass with steely blue blades that brings texture and movement. Drought-hardy and deer resistant, it pairs beautifully with succulents.
If you are also planning vertical interest around your ground cover beds, consider companion plantings such as flowers that like full sun and bloom all summer for colorful borders, or drought tolerant perennials that bloom all summer to layer height and season-long color over your low carpet.
Quick Comparison: Matching Plant to Site
| Plant | Spread Habit | Best Use | Value Tier |
|---|---|---|---|
| Creeping Thyme | Low mat, slow to moderate | Path cracks, stepping stones | Entry-level |
| Sedum | Dense carpet, moderate | Rock gardens, gravel beds | Entry-level |
| Ice Plant | Rapid spreader | Slopes, coastal sites | Mid-range |
| Lantana | Shrubby, fast filler | Large bare patches, pollinator gardens | Mid-range |
| Creeping Juniper | Spreading evergreen | Banks, erosion control | Premium |
| Blue Fescue | Clumping, non-spreading | Accent rows, mixed borders | Premium |
How to Plant and Establish Your Ground Cover
Success with drought-tolerant covers is mostly about preparation and patience during the first season. Follow these steps for a strong start:
- Test drainage first. Most drought-tolerant plants rot in waterlogged soil. If your site holds water, amend with grit or build a slight mound. Our drainage solutions guide covers fixes for stubborn wet spots.
- Clear and loosen. Remove weeds thoroughly, then loosen the top few inches of soil. You do not need rich, heavily amended soil — lean conditions actually suit these plants.
- Space correctly. Follow the recommended spacing for the species. Fast spreaders can go slightly farther apart; slow mat-formers should be planted closer for quicker coverage.
- Water through establishment. Water regularly for the first few weeks, then taper off gradually over the first growing season. This encourages deep roots.
- Mulch lightly. A thin layer of gravel or coarse mulch helps suppress weeds without trapping moisture against stems. Avoid heavy organic mulches that stay soggy.
- Be patient. Drought tolerance is earned, not instant. Once rooted, most of these plants need only occasional deep watering during extreme dry spells.

Design Ideas for Sun-Baked Areas
Ground covers shine in the toughest parts of the landscape. Try these applications:
- Slopes and banks: Spreading junipers and ice plant hold soil and look intentional where mowing is impossible.
- Between pavers: Creeping thyme softens hardscaping and releases fragrance when stepped on. Pair with ideas from our driveway landscaping guide.
- Foundation borders: Low sedums and blue fescue create a tidy, low-water edge around the house. See foundation planting for layout tips.
- Front yard replacements: Swap thirsty turf for a drought-tolerant carpet. Our front yard landscaping resources show how to plan the transition.
- Pollinator strips: Lantana and flowering thymes feed insects while tolerating heat. Explore butterfly plants for more nectar sources.
Common Mistakes to Avoid
- Overwatering after establishment. The number one killer of drought-tolerant plants is kindness — soggy soil causes rot.
- Planting in shade. Full-sun species grown in low light become leggy, sparse, and disease-prone.
- Skipping weed prep. Young ground covers cannot outcompete established weeds. Clear thoroughly first — our crabgrass control and dandelion control guides help.
- Expecting instant coverage. Give spreading plants a full season or two to knit together.
- Rich soil. Overly fertile soil pushes soft, floppy growth that is less heat-hardy. Lean is better.

Shop Recommended SuppliesFrequently Asked Questions
How long does it take for a drought-tolerant ground cover to fill in?
Fast spreaders like ice plant and lantana can cover a patch within one to two seasons. Slower mat-formers such as creeping thyme and sedum may take two to three seasons to knit together fully. Proper spacing and good weed control speed the process considerably.
Do these plants need any water at all once established?
Most survive on natural rainfall in average climates. During prolonged heat waves or extended dry spells, a deep soak every few weeks keeps them looking their best — but they will rarely die without it. New plantings always need regular watering through their first growing season.
Can I walk on drought-tolerant ground covers?
Some, yes. Creeping thyme and certain sedums tolerate light foot traffic and work well between stepping stones. Others, like juniper and lantana, are best kept off. Match the plant to how the space will be used.
Will these plants survive in poor, sandy, or rocky soil?
Many will thrive in exactly those conditions — lean, sharply drained soil is ideal for sedum, thyme, ice plant, and juniper. The key requirement is drainage. Heavy clay that holds water is the real enemy, and amending it or building raised beds solves the problem.
Are drought-tolerant ground covers deer resistant?
Several are notably deer resistant, including creeping juniper, blue fescue, and many sedums and thymes. No plant is completely deer-proof, but these aromatic and tough-textured options are rarely browsed heavily.
