Xeriscaping in Denver: Plants, Rebates & Design for the Front Range
Denver invented the word xeriscape. Here's the complete local guide — the best plants for Zone 5b/6a, turf-replacement rebates, and designs built for Front Range conditions.
Xeriscaping in Denver isn't a trend — it's a homecoming. The word itself was coined by Denver Water in 1981, and no city has better reasons to use it: the Front Range gets roughly 15 inches of precipitation a year, less than half of what a Kentucky bluegrass lawn wants. Every summer, Denver homeowners pour treated drinking water onto grass that was never meant to grow here. Here's the complete local guide to doing it differently.
Denver's growing conditions (know before you plant)
- Hardiness zone: 5b to 6a. Much of metro Denver shifted to 6a on the current USDA map, but cold snaps still argue for zone-5 toughness in exposed spots. (New to zones? Read our hardiness zone guide.)
- Semi-arid climate — intense sun at altitude, drying winds, and dramatic temperature swings, including midwinter warm spells that stress shallow-rooted plants.
- Clay-heavy soils across much of the metro. Most natives handle it; amend planting beds with compost, but don't over-pamper — lean soil keeps xeric plants tough and tidy.
- Hail happens. Fine-textured and strappy-leaved plants shrug it off better than big-leaved ornamentals.
The best xeriscape plants for Denver
Proven, locally loved, and matched to Front Range conditions:
Perennials: catmint (Nepeta), penstemon (try Rocky Mountain penstemon — a native), yarrow, agastache (hummingbird mint), chocolate flower, blanket flower, evening primrose, and salvia. All bloom hard on minimal water once established.
Grasses: blue grama (Colorado's state grass — also a lawn alternative), little bluestem, and switchgrass for height and winter structure.
Shrubs: rabbitbrush (electric gold in fall), Apache plume, fernbush, manzanita (evergreen groundcover types like 'Panchito'), and three-leaf sumac.
Trees: hackberry, bur oak, Kentucky coffeetree, and pinyon pine all earn their water.
Groundcovers: ice plant, creeping veronica, and sulphur buckwheat fill gaps and suppress weeds.

Denver rebates: get paid to lose the lawn
Colorado has leaned hard into turf replacement, and Denver-area homeowners have real money available:
- Denver Water and regional partners run turf-replacement and water-wise landscape programs — check their current offerings before you touch the lawn.
- Resource Central (Boulder-based nonprofit serving the Front Range) offers lawn removal services and famously affordable pre-designed Garden In A Box kits, often discounted through local utilities.
- Colorado's statewide turf replacement program funds local buyback programs across the metro — most suburban utilities (Aurora, Castle Rock, Westminster, and others) run their own versions with per-square-foot payments.
The one rule: apply before you remove any grass. Nearly every program requires pre-approval with photos of the living lawn.
Design notes for the Front Range look
The best Denver xeriscapes don't imitate Phoenix — they look like Colorado:
- Boulders and flagstone read native here; pair with steppe-style drifts of grasses and flowering perennials.
- The hell strip — that baked stretch between sidewalk and street — is Denver's classic first project. It's brutal for turf and perfect for xeric plants.
- Design for winter. Ornamental grasses, seed heads, and evergreen structure keep the yard alive-looking through brown months.
- Keep some green if you want it — a small blue grama or buffalograss patch stays soft underfoot at a fraction of bluegrass water. Compare options in our lawn vs. xeriscape breakdown.
Getting started
- Measure your thirstiest zone (usually the front lawn or hell strip).
- Check rebate programs and get pre-approved.
- Follow the 10 Steps to Xeriscaping — plan, kill the grass, amend, plant in fall or spring, drip-irrigate, mulch.
- Water deeply the first season, then wean.

Denver gave xeriscaping its name. A Front Range yard full of penstemon, blue grama, and rabbitbrush isn't a compromise — it's what this place actually looks like when you let it.
