Xeriscape Design in Denver: A Step-by-Step Process Guide

Most homeowners come to xeriscape design the same way: they're done with the lawn, they've seen a neighbor's yard that looks great, and they want that — but they have no idea how to get from where they are to there. What's the process? What decisions do you actually make? What does a designer do that you couldn't do yourself?

This guide walks through the full xeriscape design process in Denver — from the first site assessment to the final planted bed — and explains what's involved at each step. It's the same process we use on every project in our custom landscape design service. If you're still figuring out what a landscape design should include, what it costs, and how to pick a designer, start with our overview of landscape design in Denver.

Step 1: Site Assessment

Good xeriscape design starts with reading the site, not picking plants. Before anything else, a designer looks at:

• Sun exposure: Which areas get full sun (6+ hours), partial sun (3–6 hours), and shade? This determines which plants can go where — and where you'd waste water trying to grow something in the wrong light.
• Soil: Denver's native soil is typically clay-heavy, which drains poorly and compacts easily. A soil assessment tells you what amendment is needed and whether any areas have drainage problems that need to be addressed in the design.
• Existing irrigation: Where are the existing irrigation lines? Can they be repurposed for drip, or do they need to be capped and replaced?
• Grade and drainage: Where does water flow after rain? Low spots that collect water need a different plant palette than fast-draining slopes.
• Micro-climates: South-facing walls radiate heat and stay warmer in winter. North-facing beds stay cool and wet longer into spring. These micro-climates affect plant performance significantly in Denver.

Step 2: Defining Goals and Style

Before plant selection, the designer needs to understand what the homeowner is trying to accomplish. This sounds obvious, but most homeowners haven't articulated it clearly. Common goals in Denver xeriscape projects:

• Curb appeal: The front yard is the primary driver — the goal is something that looks designed and attractive while cutting the water bill.
• Privacy: Taller native shrubs and ornamental grasses used strategically to screen sightlines from the street or neighbors.
• Pollinator habitat: A garden designed around flowers that bloom in sequence from April through September, supporting bees, butterflies, and hummingbirds.
• Low-labor retirement yard: Simplicity and durability over complexity — a design that looks good without requiring anyone to fuss over it.
• Modern/minimal: Clean lines, restrained palette, architectural plants, and gravel or DG as the primary surface.

Style matters because it shapes every subsequent decision — plant species, mulch type, layout geometry, and edging details all flow from an agreed aesthetic direction.

Design is about more than plant selection — it's sun mapping, drainage, style, and plant placement working together.

Step 3: Hydrozoning — Grouping Plants by Water Need

Hydrozoning is one of the most important principles in xeriscape design — and the one most often skipped in DIY projects. The concept: group plants with similar water needs together so the irrigation system can be optimized by zone.

A simple example: native grasses and drought-adapted shrubs on one drip zone, running every 10–14 days. Newly planted perennials needing more frequent water on a second zone. Anything near downspouts or natural drainage in a low-water or no-irrigation zone.

When plants with wildly different water needs share a zone, you end up overwatering the drought-tolerant ones to keep the thirsty ones alive — or underwatering the thirsty ones to not drown the others. Both outcomes produce a struggling, unattractive landscape. Hydrozoning prevents this.

Step 4: Plant Selection for USDA Zone 6a

Most of the Denver metro sits in USDA Hardiness Zone 6a on the 2023 map, with average winter lows of -10°F to -5°F — some warm urban pockets are 6b, and higher foothill-edge areas drop to 5b (USDA Plant Hardiness Zone Map). Plant selection has to account for both the cold winters and the hot, dry summers — a combination that eliminates many otherwise drought-tolerant plants from other regions.

The best performers for Denver xeriscape design fall into a few categories:

• Native shrubs: Rabbitbrush, fernbush, native serviceberry, four-wing saltbush — structural plants that anchor the design
• Grasses: Native blue grama and sideoats grama, plus well-behaved adapted grasses like blue fescue and feather reed grass — movement and texture
• Perennials: Blanket flower, yarrow, Rocky Mountain columbine, plus adapted catmint and salvia — color and seasonal interest
• Groundcovers: Creeping juniper, pussytoes, creeping thyme — low-growing weed suppression between larger plants

Step 5: Irrigation Design

A xeriscape design is only as good as its irrigation plan. In Denver, drip irrigation is strongly preferred over spray for planted beds — it puts water at the root zone instead of into the air, so far less is lost to evaporation and wind. It also keeps you legal: under Denver Water's 2026 drought rules, spray irrigation is prohibited from October 1, but plants can still be watered with low-volume irrigation like drip (Denver Water).

The irrigation design defines zone layout, emitter placement, spacing, and timing. Weather-based smart controllers that adjust watering to actual conditions are increasingly standard (EPA WaterSense).

The finished result: a designed xeriscape that looks intentional, performs in Denver's climate, and costs a fraction of a lawn to maintain.

What Does Xeriscape Design Cost in Denver?

Our design fee is $500, and it's credited toward the project on installs over $5,000 — so on most full-yard projects we build, the design doesn't add to the total.

For total project costs — planted xeriscape from $6/sq ft (most projects $6–10), hardscape from $8/sq ft — see our Denver xeriscaping cost guide.
