Desert & Southwest Xeriscape
Full DG Front Yard
Decomposed granite covers the entire front yard as the base layer, with 3-5 desert native plants placed at varying distances for a naturalistic look. Palo verde or desert willow as the canopy tree, a mass of brittlebush for winter-spring gold color, and an agave or saguaro as the bold focal accent. Classic Phoenix and Tucson design that is standard HOA-approved throughout the Southwest. Install boulder accents for scale and visual weight.
Cactus Garden (AZ/TX)
A curated collection of saguaro, prickly pear, barrel cactus, and cholla arranged on a bed of black lava rock mulch. Very architectural, very low maintenance, and authentically Sonoran. Space cacti for their mature size (saguaro can reach 40 ft) and arrange in odd-numbered groups. Tall saguaro at the back, mid-height barrel cactus in the middle, low prickly pear at the front. Add 2-3 statement boulders for scale.
Tucson Sonoran Native Design
A complete native plant community: saguaro as the canopy, palo verde as the secondary tree, ocotillo as the vertical accent, brittlebush as the golden groundcover, and ryeliope grass as the ground-level filler — all in a naturalistic, irregular arrangement over DG. This plant community evolved together and supports the full Sonoran Desert food web. Quails, cactus wrens, and hummingbirds will colonize within a season.
Lavender + Agave Border
Silver-blue agave anchors each end of a border planting, with lavender mass-planted between them in waves of purple. River rock mulch covers all exposed soil. The contrast of the soft lavender blooms against the rigid agave geometry is striking. Mediterranean meets desert — this combination works beautifully in zones 7-10 and requires almost no irrigation after year one. The lavender blooms in early summer; the agave provides year-round structural interest.
California & Pacific Coast
California Native Meadow
California poppy, yarrow, salvia (Salvia clevelandii or leucantha), and toyon planted together in a naturalistic meadow pattern. Seed the poppy and yarrow in fall for spring germination; plant the shrubs (toyon, salvia) as 1-gallon starts. By year two, zero irrigation is needed — these plants evolved for California's exact dry-summer, wet-winter climate. Spring bloom is spectacular: orange poppies carpeting the ground with blue salvia spikes rising above.
Mediterranean Herb Garden
Lavender, rosemary, thyme, sage, and oregano planted in gravel — the perfect xeriscape for California's Mediterranean climate. All of these plants evolved in a climate nearly identical to coastal California: hot dry summers, cool wet winters. Once established (year one with deep but infrequent watering), they need zero irrigation. Plant in gravel, not rich soil — rich soil makes Mediterranean herbs grow too fast and flop.
SNWA Rebate Landscape (Las Vegas)
The Southern Nevada Water Authority pays $3 per square foot for removing lawn and installing xeriscape — up to $3,000 for homeowners. A qualifying design includes: no lawn, drip irrigation for any new plants, DG or rock mulch, and regionally appropriate plants. A 500 sq ft lawn removal qualifies for $1,500 in rebates. The net cost of a proper xeriscape install can be near zero after rebates. Contact SNWA before starting.
Colorado & Mountain West
Denver Water Smart Yard
Buffalo grass (Buchloe dactyloides) as a lawn alternative — native to the Great Plains, goes dormant in winter but uses 75% less water than bluegrass. Surround with a mixed perennial border of penstemons (blue, red, pink), blanket flower (gaillardia), yucca, and blue grama grass. Denver Water offers free design consultations and plant vouchers for water-smart gardens. A front yard completely transformed for Colorado's climate.
Colorado Xeriscape Mixed Shrub
Gamble oak (Quercus gambelii) as the canopy, blue grama grass as the low groundcover, rabbitbrush (Ericameria nauseosa) for fall gold color, and penstemon (various species) for spring color spikes. This plant community mirrors Colorado's foothills landscape. All plants are native and require zero irrigation after the first season. The rabbitbrush's fall gold is spectacular against the blue grama and the oak's autumn orange.
Ornamental Grass + Boulder Design
Large clumps of blue oat grass (Helictotrichon sempervirens), feather reed grass (Karl Foerster), and blue grama grass planted around limestone boulders in varying sizes. The blue-silver foliage of the oat grass against warm limestone creates a stunning color palette. All grasses are drought-tolerant and cold-hardy to zone 4. Cut back in March; by June the grasses are full and beautiful again. Zero irrigation needed after establishment.
Texas & Southeast
Texas Heat Zone Garden
Texas sage (Leucophyllum frutescens) as the anchor shrub — it blooms in response to humidity, often predicting rain 48 hours before it arrives. Salvia greggii for hummingbirds, lantana for butterflies, black-eyed Susan for summer color, and Pride of Barbados for tropical drama. All thrive in Texas's alkaline, rocky soil and intense summer heat. Use decomposed granite mulch, not wood chips — it stays cooler and doesn't attract termites.
Native Wildflower Meadow
Bluebonnet (Lupinus texensis), Indian paintbrush (Castilleja indivisa), Mexican hat (Ratibida columnifera), and Maximilian sunflower (Helianthus maximiliani) seeded in fall for a spectacular spring display. Scatter seed over prepared (scraped, not tilled) soil in October-November. Zero irrigation after germination. The spring bloom runs February through May in zones 8-9. After bloom, leave seed heads to self-sow for next year. Annual wildflower cost after year one: $0.
Rock Mulch + Texas Natives
Light-colored limestone gravel mulch reflects heat and light rather than absorbing it — crucial in Texas summers where soil temperature under dark mulch can exceed 150°F. Plant heat-tolerant natives: cenizo (Texas sage), blackfoot daisy, winecup (Callirhoe involucrata), and green cloud Texas sage. The white gravel creates a bright, Mediterranean-inspired aesthetic while keeping plant roots cooler than any other mulch type.
7 Principles of Xeriscape
The seven principles of xeriscape were developed by Denver Water in 1981 and adopted by water utilities worldwide. Apply all seven for a genuinely water-efficient landscape.
| # | Principle | Description | How to Apply |
|---|---|---|---|
| 1 | Planning & Design | Start with a water-efficient design before buying plants | Group plants by water needs; sketch the layout first |
| 2 | Soil Improvement | Improve soil water retention with compost | Add 2-3 inches compost before planting |
| 3 | Limited Turf | Reduce or eliminate water-hungry lawn | Replace with groundcovers, gravel, or native meadow |
| 4 | Water-Efficient Plants | Use drought-adapted native and adapted plants | Choose plants rated for your zone that need no supplemental water after year 1 |
| 5 | Efficient Irrigation | Drip irrigation delivers water to roots, not leaves | Install drip for new plant areas; remove spray heads in lawn-replaced areas |
| 6 | Mulching | 3-inch mulch layer reduces evaporation 70% | Use wood chip, DG, or rock mulch everywhere |
| 7 | Maintenance | Xeriscape is not no-maintenance — just low-maintenance | Weed once/season; prune native shrubs annually |
Lawn vs. Xeriscape Water Use
Based on average 1,500 sq ft front yard at $0.005/gallon water rate. Year 1 xeriscape use is higher due to plant establishment; year 2+ the savings compound.
| Year | Lawn Use (gallons) | Xeriscape Use (gallons) | Savings (gallons) | Annual Savings ($) |
|---|---|---|---|---|
| Year 1 | 50,000 | 15,000 | 35,000 | $175 |
| Year 2 (established) | 50,000 | 5,000 | 45,000 | $225 |
| 10 Year Total | 500,000 | 65,000 | 435,000 | $2,175 |
