Hey there, desert gardeners! Tim Burr here, and today we're getting low — as in groundcover low. Because here's a truth about Phoenix landscapes that doesn't get enough attention: what's happening between your showpiece trees and shrubs matters just as much as the stars of the show.
The right groundcover in a Phoenix yard does an incredible amount of work. It suppresses weeds (so you're not pulling them every weekend). It retains moisture in the soil (cutting your water use). It moderates soil temperature (protecting roots during extreme heat). And it fills in the visual 'floor' of your landscape, making everything look intentional and designed rather than sparse and unfinished.
The wrong choice — or just bare gravel everywhere — leads to a yard that always looks half-done, runs hot at ground level, and turns into a weed battlefield every monsoon season. Let's pick the right ones.
What Makes a Great Groundcover for Phoenix?
Not every low-growing plant earns the title 'groundcover' in a desert landscape. Here's what the best Phoenix groundcovers share:
- Spreads reliably without being invasive: Coverage is the job. The plant should fill in reasonably quickly without escaping into native desert or neighboring properties.
- Extremely drought-tolerant once established: A groundcover that needs constant irrigation negates one of its main benefits — water conservation.
- Handles heat and reflected sun: Ground level in a Phoenix yard in July is brutal. The rock and soil surface can hit 180°F+. Groundcovers need to handle this.
- Low maintenance: Groundcovers should simplify your landscape, not add work. The best ones need occasional trimming at most.
- Bonus: color or fragrance: When a groundcover also produces flowers, fragrance, or interesting foliage color, it elevates the entire landscape.
The Top Groundcovers for Phoenix — Available at Three Timbers
New Gold Lantana
- New Gold Lantana — The gold standard of Phoenix groundcovers — pun absolutely intended. New Gold Lantana produces non-stop golden-yellow flowers from spring through fall, spreads reliably to 3–4 feet wide, handles extreme heat without complaint, and attracts butterflies by the dozens. It's tough, colorful, fast-spreading, and requires almost no maintenance beyond an annual trim. A must-have. [threetimbersshop.com/collections/groundcovers-sprawling-plants]
Purple Trailing Lantana
- Purple Trailing Lantana — Vivid purple-lavender flowers on cascading stems that trail beautifully over walls, down slopes, or across open ground. Pairs magnificently with New Gold Lantana for a warm-purple color contrast. Same toughness, same drought tolerance, same butterfly magnetism — different color story. Use them together for a show-stopping ground layer. [threetimbersshop.com/collections/groundcovers-sprawling-plants]
Dallas Red Lantana
- Dallas Red Lantana — Fiery red-orange-yellow flower clusters that warm up any planting. Slightly more upright than trailing forms, making it a great mid-level groundcover or low-border plant. Blooms continuously from spring through late fall in Phoenix conditions and handles the hottest months with ease. [threetimbersshop.com/collections/groundcovers-sprawling-plants]
Mexican Evening Primrose (Oenothera speciosa)
- Mexican Evening Primrose — A soft, romantic groundcover with delicate pink flowers that open in the morning and last through the day. Blooms prolifically in spring and periodically through summer. Mexican Evening Primrose spreads via underground runners — excellent for filling large areas, but keep it away from beds where it might crowd out less aggressive plants. Extremely drought-tolerant and gorgeous in mass plantings. [threetimbersshop.com/collections/groundcovers-sprawling-plants]
Mediterranean Carpet (Dymondia margaretae)
- Mediterranean Carpet — The ultimate low, flat groundcover for between pavers, around stepping stones, or as a lawn substitute in small areas. Mediterranean Carpet grows only 1–2 inches tall, handles foot traffic, produces tiny yellow flowers, and tolerates heat and drought extremely well. It's the closest thing to a no-mow, no-fuss 'floor' for a Phoenix landscape. [threetimbersshop.com/collections/groundcovers-sprawling-plants]
Moss Verbena (Glandularia pulchella)
- Moss Verbena — Delicate, ferny foliage topped with lavender-purple flowers nearly year-round in the mild Phoenix climate. Moss Verbena trails gracefully, self-seeds gently to fill in gaps, and has a soft, naturalistic texture that pairs beautifully with more structural plants like agave or desert spoon. Low-water and native-bee friendly. [threetimbersshop.com/collections/groundcovers-sprawling-plants]
Purple Heart (Tradescantia pallida)
- Purple Heart — One of the most striking foliage groundcovers for Phoenix — deep purple leaves that provide year-round color contrast even when the plant isn't in bloom. Small pink flowers add seasonal charm. Purple Heart can burn back in the most extreme summer heat but recovers quickly. Particularly dramatic when planted against white walls or light-colored rocks. [threetimbersshop.com/collections/groundcovers-sprawling-plants]
Bush Morning Glory (Convolvulus cneorum)
- Bush Morning Glory — Silvery-gray foliage and white-pink morning glory flowers on a low, spreading mound. Bush Morning Glory is extremely drought-tolerant, looks clean and tidy year-round, and has a reflective quality to its leaves that actually bounces some of the intense Phoenix sun. Excellent as a groundcover in hot, south or west-facing exposures where other plants struggle. [threetimbersshop.com/collections/groundcovers-sprawling-plants]
🌵 Tim's Tip: For the fastest groundcover fill-in, plant at closer-than-normal spacing and water consistently for the first summer. Once established, back off the water and let them spread naturally. The cost of closer spacing upfront is offset by having a filled, weed-suppressing ground layer by the end of year one.
Groundcovers vs. Gravel: The Great Phoenix Debate
This comes up a lot. Gravel is the dominant 'groundcover' in Phoenix — and it has real advantages: zero maintenance, immediate coverage, clean look. But living groundcovers offer things gravel never will:
- Temperature moderation: Gravel can reach 170–190°F on a Phoenix summer day. Living groundcovers stay significantly cooler through transpiration, which also lowers the ambient temperature in the surrounding landscape.
- Weed suppression: Well-established groundcovers crowd out weeds far better than gravel, which seeds in with every monsoon and requires constant re-application of pre-emergent.
- Wildlife value: Groundcover flowers feed bees, butterflies, and hummingbirds. Gravel feeds nothing.
- Aesthetic richness: A living ground layer gives texture, color, and life to a landscape. Gravel is clean and easy — but it never changes, never flowers, never surprises you.
The best Phoenix landscapes typically use both: gravel as the base material in open areas, living groundcovers in planted beds and around trees and shrubs. The combination is functional, water-smart, and visually rich.
Slope & Erosion Control with Groundcovers in Phoenix
One of the most practical uses for groundcovers in Valley yards is slope stabilization. Phoenix yards often have elevation changes, berms, or sloped areas that erode badly during monsoon downpours. Living groundcovers with dense root networks hold soil in place far better than gravel or bare rock.
- Mexican Evening Primrose: Fast-spreading with underground runners — excellent slope stabilizer
- Trailing Lantana: Dense ground-hugging stems and moderate root system handle modest slopes well
- Moss Verbena: Particularly good on natural-looking desert slopes for a seamless integration with the surrounding landscape
