Types of Groundcover Suited To Arizona Landscaping

Arizona encompasses a wide variety of climates, from the low-elevation Sonoran Desert around Phoenix and Yuma to higher-elevation pine and ponderosa forests near Flagstaff. Selecting suitable groundcovers requires matching plants to microclimates, soil types, sun exposure, water budgets, and intended use (erosion control, pollinator habitat, walkways, or purely ornamental). This article catalogs practical groundcover types and specific species that perform well in various Arizona settings, plus concrete planting, irrigation, and maintenance guidance for long-term success.

Climate zones and site assessment

Arizona is not a single climate. Before planting groundcover, assess your site on these key variables:

• Sun exposure: full sun, part sun/part shade, or full shade.
• Elevation and winter lows: low desert (hot, mild winters), high desert and mountain areas (cold winters, possible snow).
• Soil texture and drainage: sandy, rocky, clay, or compacted urban soils.
• Water availability and irrigation method: drip irrigation, spray, or none.
• Foot traffic and intended use: pathways, occasional stepping, or purely decorative.

Match plants to those conditions. A plant that thrives in Flagstaff may fail in Phoenix and vice versa.

Categories of groundcover suited to Arizona

Drought-tolerant native and Mediterranean-type groundcovers

These species conserve water, tolerate heat, and suit low-desert and transitional zones.

• Dymondia (Dymondia margaretae): Low silver-green mat, 1-3 inches high, spreads 1-2 feet. Excellent heat tolerance and good for moderate foot traffic. Use in full sun, well-drained soils. Establishment takes a season; once established water very sparingly.
• Creeping Lippia (Phyla nodiflora / Lippia repens): Dense evergreen mat 1-3 inches tall with small white flowers that attract pollinators. Spreads by stolons, tolerates light foot traffic and occasional irrigation. Good for low-desert lawns or mass planting.
• Trailing Lantana (Lantana montevidensis): Purple/lavender flowers, trailing habit 6-12 inches tall. Drought tolerant, fast-spreading; useful on slopes and banks. Can be aggressive in favorable conditions.
• Gazania (Gazania rigens and hybrids): Colorful daisy-like flowers, low evergreen clumps 6-8 inches tall. Excellent sun and heat tolerance, moderate drought tolerance. Retracts flowers in low light.

Succulent and rock garden groundcovers

Succulents conserve water, tolerate heat, and look appropriate in desert rockscape beds.

• Ice plant / Delosperma (various species): Flowering succulent mats with vivid colors. Very drought tolerant and low-growing. Use where winter lows are moderate; some varieties tolerate high-elevation cold better than others.
• Sedum groundcovers (Sedum spurium, Sedum album forms): Low mats, good for rock gardens, tolerates heat and sun when well-drained. Choose varieties rated for your minimum winter temperature.
• Aptenia cordifolia (Baby Sunrose): Bright succulent groundcover with red flowers; prefers full sun or light shade. Tolerates heat but can be frost sensitive in colder parts of Arizona.

Turf alternatives and ornamental grasses

For people wanting a green, mowable surface or very low-water turf substitute.

• Buffalograss (Bouteloua dactyloides): Warm-season native grass that forms a low lawn. Needs fewer mowings and much less water than Kentucky bluegrass. Performs best in low- to mid-elevation Arizona.
• Blue grama (Bouteloua gracilis): Fine-textured native grass, low clumping habit. Excellent drought tolerance and ideal for prairie-style landscapes and erosion control.
• Dichondra (Dichondra repens and D. micrantha): Low, kidney-leaf groundcover used as a lawn alternative in mild climates. Requires more water and fertilization than many succulents; works in shaded yards.

Shade-tolerant and under-tree groundcovers

Many desert yards have shade under trees or covered patios where sun-loving species will fail.

• Liriope (Liriope muscari and L. spicata): Clumping, grass-like perennial that tolerates part shade, urban soils, and moderate drought. Good for borders and under trees.
• Native sedges and carex species: In cooler or moister microclimates, some sedges provide dense, low covers with low maintenance.
• Purslane (Portulaca oleracea varieties selected for ornamental use) can handle sun but also survives in partial shade.

Plant selection by use case

High-traffic areas and pathways

Choose resilient mats or turf alternatives that recover from compaction.

• Dymondia for stepping areas and low-traffic patios.
• Buffalograss or blue grama for informal lawns that will be mowed.
• Gravel with stepping-stones plus interstitial plantings of creeping thyme or Lippia for narrow paths.

Erosion control on slopes

Use fast-spreading, deep-rooted groundcovers.

• Creeping lantana and gazania work on sunny slopes.
• Native bunch grasses and blue grama for stabilization in arid soils.

Pollinator and wildlife gardens

Choose flowering groundcovers that bloom over long periods.

• Creeping lippia (Phyla) and gazania attract bees and butterflies.
• Native flowering buckwheats and low-growing perennials can be used as complementary plantings.

Practical planting, soil, and irrigation guidance

Planting time and spacing

• Plant in fall or early spring in most of Arizona. Fall plantings allow roots to establish before the first summer heat in low desert, and before winter freezes in high desert.
• Space plants according to spread and desired fill time: 6-12 inches for fast-spreading mats (Dymondia/lippia), 12-24 inches for slower sedum or gazania patches. Tight spacing reduces weed pressure.

Soil preparation

• For succulents and ice plants, ensure excellent drainage. Amend heavy clay with coarse sand or grit and avoid rich organic mixes that retain moisture.
• For native prairie grasses and buffalograss, minimal amendment is best; they prefer poorer soils. Over-fertilizing increases water needs.
• Test soil pH if you suspect extremes. Many desert-adapted groundcovers tolerate alkaline soils common in Arizona.

Irrigation and establishment

• Establishment period: water new plantings regularly for 2-3 months to develop roots. In summer low desert, this typically means light, frequent irrigation initially, tapering to deeper, less frequent watering after 6-12 weeks.
• Long-term irrigation: use drip irrigation with low-flow emitters for most groundcovers. For turf alternatives, use a separate sprinkler schedule.
• Reduce watering incrementally after the first year. Most recommended groundcovers are low-water once established.

Mulch and heat management

• Use rock or decomposed granite mulch to match desert aesthetics and reduce evaporation. Keep mulch a few inches away from plant crowns to avoid rot.
• Beware that dark rocks absorb heat; in extreme low-desert exposures, reflective or light-colored rock can reduce heat stress for newly established plants.

Maintenance and long-term care

• Minimal fertilization: most drought-tolerant groundcovers need little or no fertilizer. If growth is thin after establishment, a light annual application of balanced slow-release fertilizer in spring is sufficient.
• Pruning and renewal: trim trailing lantana and gazania after bloom flushes to tidy beds. Divide clumping groundcovers like liriope every 3-4 years.
• Weed control: dense spacing and established mats suppress weeds. Hand-weed early and consider pre-emergent herbicide with caution around desirable groundcovers.
• Pests and disease: watch for root rot in poorly drained soils and powdery mildew in shaded, humid microclimates. Use proper siting and water management to prevent problems.

Practical takeaways

1. Match plant to microclimate: low desert, transitional, or high desert. What thrives in Flagstaff may fail in Phoenix.
2. Prioritize drainage for succulents and minimal amendment for native grasses; too much organic matter increases water needs.
3. Use drip irrigation for beds and dedicated sprinkler zones for turf alternatives. Allow plants to establish before cutting back water.
4. Choose groundcovers based on use: Dymondia and buffalograss for traffic; Lippia and gazania for pollinators and color; sedums and ice plants for rock gardens.
5. Plant in fall or early spring, space to encourage quick fill, and maintain with minimal fertilizer and periodic pruning.

Selecting the right groundcover for an Arizona landscape reduces water demand, minimizes maintenance, stabilizes soil, and increases usable outdoor space. With the proper species selection, soil preparation, and irrigation strategy, groundcovers can be both functional and beautiful across Arizona’s diverse environments.
