Low Water, High Impact: How to Build a Drought-Tolerant Denver Landscape That Actually Looks Stunning
Xeriscaping in Denver isn’t rocks and cactus. It’s a layered, colorful, habitat-friendly outdoor environment that uses far less water than a traditional lawn. Denver Water coined the term in the early 1980s, and the approach has only grown more relevant as our regional climate pressures intensify. At Phase One Landscapes we call it a Coloradoscape: a landscape built to thrive here, not just survive.
Most Denver homeowners who come to us expecting a sparse, gravel-covered yard leave that misconception behind quickly. What we actually build is something lush and intentional, with ornamental grasses catching the afternoon light, flowering perennials drawing pollinators, and shrubs that hold color from May through October. The goal is beauty and water efficiency at the same time, not a trade-off between them.
This page covers what xeriscape really is, why Denver homeowners are converting now, what the water savings actually look like in numbers, which plants perform best on the Front Range, how our design-build process works from site analysis through post-installation care, and what a professional xeriscape investment realistically involves. If you’re researching xeriscaping in Denver, this is the straightforward guide we’d want you to have.
What Is Xeriscaping? A Denver-Specific Answer
Xeriscaping is a landscape design approach that dramatically reduces outdoor water use through intentional plant selection, efficient irrigation, and smart site planning. It doesn’t eliminate plants. It replaces thirsty, high-maintenance turf with drought-adapted species that are layered, colorful, and good for local wildlife.
Denver Water coined the term in the early 1980s in direct response to regional water shortages, combining “landscape” with the Greek word for dry. That origin matters: water-wise landscaping wasn’t invented as a trend. It was a practical response to conditions the Front Range has always faced.
The Colorado River Basin megadrought has reinforced that urgency at a policy level. Many municipalities across the Front Range now actively discourage large, high-water lawns. Some offer turf-removal rebates to accelerate the shift.
One misconception worth addressing directly: zero-scape and xeriscape aren’t the same thing. Zero-scape removes all plant material and replaces it with rock or hardscape. Xeriscape uses drought tolerant plants thoughtfully placed to create a living, breathing outdoor environment that simply needs far less water than Kentucky bluegrass. The result, when properly designed, is often more visually interesting than a traditional lawn.
Why Denver Homeowners Are Converting to Xeriscape Now
Three pressures have pushed Denver homeowners toward water wise landscaping Denver-wide, and they’re all accelerating at once.
The first is water cost and scarcity. Denver sits at high altitude in a semi-arid climate that depends on the Colorado River Basin snowpack for its water supply. That snowpack has been unreliable, and water rates reflect that reality. Outdoor irrigation accounts for a large share of residential water use, and traditional turf lawns are among the thirstiest features a property can have.
The second is municipal policy. Across our service communities, including Denver, Cherry Hills Village, Greenwood Village, Littleton, Highlands Ranch, Parker, Castle Rock, and Boulder, local water authorities are increasingly offering financial incentives to remove high-water turf and discouraging its installation in new projects. That policy direction isn’t reversing.
The third is property value and daily livability. A well-designed xeriscape adds curb appeal without the weekly mowing, the seasonal fertilizing, and the high summer irrigation bills. It performs better in Denver’s climate than a turf lawn does during the dry months of July and August. And when designed by a firm with real Front Range experience, it looks beautiful year-round.
This isn’t a landscaping trend. It’s an adaptation to conditions Denver homeowners have always faced. The difference now is that the tools, the plant palette, and the design knowledge to execute it well are more refined than they’ve ever been.
The Real Water Savings: What the Numbers Look Like in Denver
Denver Water data makes the return on investment case clearly. Xeriscaping typically saves Denver homeowners 50 to 75 percent of their outdoor water use compared to traditional turf-heavy yards.
Converting Kentucky bluegrass saves roughly 19 to 33 gallons of water per square foot per year. That translates to approximately $0.36 per square foot annually in water bill savings. At 1,000 square feet converted, that’s roughly $360 per year, every year, compounding over the life of the landscape.
The savings scale directly with how much turf you replace. A 2,500-square-foot conversion produces savings approaching $900 annually. Over a ten-year period, the water savings alone begin to offset a meaningful portion of the original installation investment. We’ll talk about what that investment looks like later in this page.
The Seven Principles of Xeriscape Design Applied to Colorado
Denver Water’s original seven xeriscape principles are the foundation every credible xeriscape design should follow. Here’s how they apply specifically to Front Range conditions:
- Planning and design. Site analysis comes before any plant selection. We evaluate sun exposure, drainage patterns, slope, soil type, and how you actually use the space. Our article on designing for Denver microclimates goes deeper on why this step is non-negotiable in a climate as variable as Colorado’s.
- Soil improvement. Denver soils are frequently clay-heavy, compacted, and slow-draining. Amendments are not optional here. The right soil preparation supports root development and water infiltration, which directly affects plant survival and long-term performance.
- Efficient irrigation. Drip irrigation and targeted low-volume systems deliver water directly to the root zone, where it belongs. Broadcast sprinklers waste water through evaporation and overspray. We design every irrigation system around hydrozones so water goes exactly where plants need it.
- Appropriate plant selection. Denver’s USDA hardiness zones range from 5b to 7a depending on location and microclimate. Native and climate-adaptive species selected for this range establish faster, tolerate our freeze-thaw cycles, and require far less supplemental water once they’re established.
- Practical turf areas. Turf has a place in a well-designed landscape: where it’s actively used for play, pets, or gathering. What it doesn’t need to be is default filler coverage for every open area of the yard.
- Mulching. A proper mulch layer conserves soil moisture, moderates temperature extremes, and suppresses weeds. In a Denver xeriscape, mulching is both a water conservation tool and a plant health strategy.
- Maintenance. Xeriscape is lower-maintenance than a traditional lawn, not zero-maintenance. Seasonal pruning, irrigation checks, and periodic re-mulching keep the landscape performing well year after year.
Colorado Xeriscape Plants Worth Knowing: A Curated Front Range List
The right plant list for a Colorado xeriscape depends on your specific site. That said, these are species we know perform well across Front Range conditions, drawn from our experience designing and building in Denver and surrounding communities.
For the full picture on plant performance in Denver’s soils and climate, our guide to plant selection for Denver landscapes goes deeper on selection and establishment.
Ornamental Grasses
- Blue Grama (Bouteloua gracilis): A Colorado native that thrives in dry, open conditions and produces distinctive eyelash-shaped seed heads that add late-season texture.
- Feather Reed Grass (Calamagrostis x acutiflora): Upright, structural, and adaptable; provides vertical interest and winter presence in a mixed planting.
- Buffalo Grass (Bouteloua dactyloides): An excellent low-water turf alternative for functional lawn areas, requiring significantly less irrigation than Kentucky bluegrass.
Flowering Perennials
- Apache Plume (Fallugia paradoxa): A semi-shrubby perennial with white flowers and feathery pink seed heads; tough, drought tolerant, and striking in mass plantings.
- Black-eyed Susan (Rudbeckia hirta): Bright, long-blooming, and familiar; one of the most reliable performers for adding color to drought tolerant planting designs.
- Salvia (Salvia nemorosa): Reliable purple spikes from late spring through fall; pollinator-friendly and extremely low-water once established.
- Penstemon (Penstemon strictus): Colorado’s own native beardtongue; tubular purple-blue flowers that hummingbirds find irresistible and that thrive in lean, dry soil.
- Catmint (Nepeta x faassenii): Soft gray-green foliage with lavender flower spikes; long-blooming, drought tolerant, and a workhorse in the perennial border.
Shrubs and Groundcovers
- Rabbitbrush (Ericameria nauseosa): A high-altitude native that explodes with bright yellow flowers in late summer when many other plants are winding down.
- Low Grow Sumac (Rhus aromatica ‘Gro-Low’): A spreading groundcover shrub with good fall color and strong drought tolerance once established; works well on slopes and as a lawn replacement in sunny areas.
- Yucca (Yucca glauca): A Colorado native with bold, spiky form and tall cream flower stalks in early summer; thrives in dry, lean soil and adds year-round structure to xeriscape plantings.
- Sedum (Sedum spp.): Low-growing and nearly indestructible in Front Range conditions; provides textural contrast, late-season color, and reliable ground coverage with minimal water.
Plant selection must match your specific site conditions. Sun exposure, drainage, soil depth, and microclimate all influence which species will actually perform versus struggle.
Why Plant Selection Alone Is Not a Xeriscape Plan
We hear this regularly: a homeowner removes their lawn, puts in some native plants, and then wonders why their xeriscape plans aren’t working. The plant list isn’t the plan, it’s only one layer of the plan.
Without hydrozone planning, plants with different water needs end up in the same irrigation zone. Some get too much water, others not enough. Without drainage analysis, poorly draining areas become problem zones where even drought-tolerant species struggle during wet springs. Without a calibrated drip system, the right plant in the wrong watering regime fails anyway.
Homeowners who DIY or work with a design-only firm frequently run into this problem. They get a planting plan, but no one handles the irrigation design, the soil amendments, or the site drainage before anything goes in the ground. The result is poor establishment, plant loss, and frustration.
We handle all of that before a single plant goes in. The site analysis, hydrozone plan, irrigation design, and construction are part of one integrated process, managed by the same team from start to finish.
How We Approach Xeriscape Design and Construction in Denver
As a fully in-house operation, Phase One Landscape’s approach to Denver xeriscape planting projects follows a clear, accountable sequence. There are no handoffs to outside builders and no gaps between what was designed and what gets built.
Here’s what that looks like in practice for a typical xeriscape project:
- Initial consultation and site analysis: We meet on-site to evaluate soil conditions, drainage patterns, sun mapping, slope, and your goals for the space. What you want to use it for matters as much as what it looks like.
- Hydrozone planning: We group areas of the property by water need. This step is what makes the irrigation system efficient and what gives plants the right conditions to establish and thrive.
- Design development: Our designer develops the plant palette, hardscape integration, drip irrigation layout, and mulching plan. You review it with the same person who will manage your project through construction.
- Construction: Our in-house crew builds what our team designs with no handoffs, no interpretation gaps, and no subcontracted builders working from someone else’s drawings. Our landscape construction and landscape design processes operate as one integrated workflow.
- Irrigation installation and calibration: An in-house irrigation specialist handles the system setup, zoning, and calibration to match the hydrozone plan. This isn’t subcontracted out.
- Plant establishment monitoring: Our irrigation specialist checks in on the installation for three to four weeks post-installation, adjusting watering as plants establish.
- 30-day satisfaction check-in and warranty coverage: We follow up at 30 days, and every xeriscape we build is backed by a one-year warranty on all plant material and a two-year limited warranty on hardscape work.

What a Professional Xeriscape Investment Looks Like
Professional xeriscape design is a real financial commitment, and understanding what drives cost helps homeowners plan honestly.
Our typical first-time project sweet spot is $80,000 to $120,000 for a full site project, with a minimum project size of approximately $20,000. Estate-level work scales from $350-500K. What moves cost up or down: total square footage being converted, existing site conditions and any demolition required, plant selection and material grade, hardscape integration, irrigation system complexity, and the scope of design work involved.
We price at fair market value, tot the cheapest quote in Denver, nor the highest. Our goal is to deliver a product worth every dollar you spend, and to be transparent about what’s driving the number before construction starts.
The long-term value case is straightforward. Water savings compound annually, and maintenance demands drop compared to a traditional lawn. A professionally designed, well-executed xeriscape improves property value and holds up over time. This is a landscape built to last in Colorado’s climate, not a lawn that fights the climate every season.

Award-Winning Xeriscape Design Built on 35 Years of Front Range Experience
Phase One Landscapes was founded in 1994, and we’ve been designing and building landscapes across the Greater Denver Metro area and the Colorado Front Range for more than three decades. We’ve worked in the neighborhoods and soil conditions that define Denver landscape construction and design: the clay-heavy lots of Cherry Hills Village, the sloped sites in Castle Rock, and wind-exposed properties on the eastern Front Range.
We’ve submitted projects to the Associated Landscape Contractors of Colorado Excellence in Landscape Awards since 1987, earning 17 awards across that body of work, including 13 Award of Excellence or Merit awards and 4 Grand Awards. Our award-winning landscape design work reflects what’s possible when site knowledge, plant expertise, and in-house construction come together in one accountable process. We also maintain active membership in both ALCC and ASLA, and we’ve state-licensed landscape architects on staff.
For xeriscaping executed at a higher level, credentials like these matter. Any firm can put together a plant list, but far fewer can design the hydrozone plan, build the irrigation system, install the hardscape, and back the whole thing with a warranty, all from one in-house team. That’s what 35 years of Denver landscape expertise actually looks like in practice.
Frequently Asked Questions About Xeriscaping in Denver
Is xeriscaping the same as zero-scaping?
No. Zero-scape removes all plant material and typically replaces it with rock or inert hardscape. Xeriscape uses carefully selected drought-adapted plants to create a living, layered, beautiful outdoor environment that uses far less water than a traditional lawn. The two approaches produce completely different results.
How much water does xeriscaping save in Denver?
Denver Water data shows xeriscaping typically saves 50 to 75 percent of outdoor water use compared to turf-heavy yards. Replacing Kentucky bluegrass saves roughly 19 to 33 gallons per square foot per year, which works out to approximately $0.36 per square foot annually. At 1,000 square feet converted, that’s roughly $360 per year in water bill savings.
Do xeriscape plants survive Denver winters?
Yes, when properly selected. Colorado native and climate-adaptive species are well-suited for Front Range freeze-thaw cycles, high-altitude wind, and temperature extremes. The key is matching the plant to the specific site conditions, which is why site analysis and plant selection go together in our process.
How long does a xeriscape project take?
Timelines vary based on scope, but a typical design-build project from initial consultation through installation runs several months. We can give you a more specific projection once we’ve assessed your site and developed the design. For more detail on timelines and processes, our FAQ page offers answers to many frequently asked questions.
Does Phase One Landscapes offer a warranty on xeriscape plants?
Yes. We back every installed xeriscape with a one-year warranty on all plant material and a two-year limited hardscape warranty. Our irrigation specialists also monitor plant establishment for three to four weeks post-installation, and we follow up with a 30-day satisfaction check-in to make sure everything is performing as it should.
