You can’t xeriscape Denver without the right plants.
Wrong plants = constant struggle, dead replacements, wasted money. Right plants = thriving yard with minimal water, low maintenance, year-round color.
The secret: native and adapted plants that evolved in Denver’s climate.
In this guide, we’ll show you exactly which plants thrive in Denver xeriscapes, organized by season, function, and growing conditions. Every plant here has proven itself in Colorado’s altitude, clay soil, and temperature swings.
This is the definitive reference for choosing native plants for your Denver xeriscape.
Why Native Plants Matter for Denver Xeriscaping
Native plants aren’t trendy — they’re practical.
A native shrub evolved on Colorado’s Front Range. It knows how to handle 14 inches of annual rainfall (Denver’s average), how to survive 500-year droughts, how to deal with heavy clay soil, how to thrive at 5,280 feet elevation, and how to endure temperature swings from 60°F to 30°F in 24 hours.
Compare that to a fancy ornamental from California or the Southeast. It’s constantly stressed. More watering, more fertilizer, more fungicide, more replacement.
Native plants = less intervention, more thriving.
The math: a xeriscape costs $10,000 upfront. Plant choice determines whether it’s a $200/year maintenance burden or completely hands-off after year 2.
Best Shrubs for Denver Xeriscaping
Shrubs are the backbone. They provide structure, year-round interest, and habitat for wildlife.
Serviceberry (Amelanchier)
Height: 12–15 ft | Sun: Full sun to part shade | Water: Low once established
Serviceberry is the unsung hero of Denver landscapes.
• Spring: Delicate white flowers appear before leaves
• Summer: Sweet edible berries (birds love them)
• Fall: Golden-orange foliage
• Winter: Interesting branch structure
Why it works: Native to Colorado Front Range, handles clay soil, thrives at altitude, practically pest-free.
Cost: $25–$60 (young) | $75–$150 (mature)
Pro tip: Plant in spring for best establishment. Grows 1–2 ft/year.
Gambel Oak (Quercus gambelii)

Ornamental Grasses for Structure and Movement
Grasses add texture, movement, and winter interest. They’re the secret to making xeriscapes look alive.
Blue Fescue (Festuca cinerea)
Height: 12–18 inches | Sun: Full sun | Water: Very low
Blue Fescue is your edging plant.

Perennials and Wildflowers for Season-Long Color
Perennials are the jewelry of xeriscapes. They provide seasonal color without the commitment of shrubs.
Lupines (Lupinus species)

Pro tip: Plant in large drifts (7–10 plants) for maximum impact. Self-seeds — you’ll get volunteers next year.
Columbine (Aquilegia species)
Height: 18–24 inches | Sun: Part shade to shade | Water: Low to moderate

Cost: $15–$35
Pro tip: Plant on slopes for erosion control. Use as a backdrop for flowering perennials.
Plant Selection by Growing Condition
Not all native plants grow everywhere in Denver. Match plants to your actual conditions.
Full Sun (6+ hours direct sun)
Best choices: Rabbitbrush, Sideoats Grama, Blanket Flower, Yarrow, Sedum, Creeping Juniper
These plants want sun and have evolved to handle intense UV at altitude.
Part Sun (3–6 hours direct sun)
Best choices: Serviceberry, Catmint, Columbine, Salvias, Festuca
These tolerate both sun and shade. Columbine especially loves afternoon shade in Denver’s intense climate.
Shade (less than 3 hours direct sun, north-facing)
Best choices: Columbine, Serviceberry, Fernbush
Most natives want sun. Columbine is your best shade option. Consider non-xeriscape approaches for deep shade.
Dry Slopes and Poor Soil
Best choices: Rabbitbrush, Gambel Oak, Fernbush, Yarrow, Pussytoes, Creeping Juniper
These plants laugh at poor soil and wind exposure.
Heavier Soils (Clay-heavy, Denver standard)
Best choices: Serviceberry, Chokecherry, Catmint, Lupines, Salvias
These tolerate and actually thrive in Denver’s clay. Soil amendment still helps, but these won’t fail in clay.
Season-Long Color Strategy
The best xeriscapes layer plants so something is blooming or interesting every month.
Spring (April–May)
• Lupines (purple-blue spikes)
• Columbine (delicate nodding flowers)
• Serviceberry (white flowers)
• Salvias (early bloomers)
Summer (June–August)
• Blanket Flower (orange-red, non-stop)
• Catmint (purple-blue)
• Yarrow (multiple colors)
• Ornamental grasses (texture and movement)
• Rabbitbrush (building to fall color)
Fall (September–October)
• Rabbitbrush (golden-yellow flowers, peak color)
• Gambel Oak (red, orange, burgundy foliage)
• Yarrow (continued bloom, warm tones)
• Sedum (foliage color shift)
• Ornamental grasses (bronze and tan seed heads)
Winter (November–March)
• Serviceberry (branch structure)
• Creeping Juniper (evergreen color)
• Ornamental grass seed heads (tan and bronze texture)
• Gambel Oak bare branches (architectural interest)
• Sedum (colorful dried foliage)
Common Plant Mistakes to Avoid
Mistake #1: Non-Native “Drought-Tolerant” Plants
A plant from Arizona or California that’s “drought-tolerant” might not survive Denver’s winter, clay soil, or altitude.
Solution: Stick with plants that evolved here or in similar climates — high altitude, clay soil, cold winters.
Mistake #2: Planting Too Dense
It’s tempting to fill gaps at planting. Plants grow. In 3–5 years you’ll have massive overcrowding, poor air circulation, and disease.
Solution: Plant for mature size. Use mulch to fill visual gaps in year 1.
Mistake #3: Wrong Plant for Your Conditions
A sun lover in shade = slow decline. A shade lover in intense sun = constant stress.
Solution: Match plant to actual sun exposure. Don’t fight your conditions.
Mistake #4: Assuming Native = Zero Water
Native plants need water their first 2 years to establish deep roots. After that, they’re nearly self-sufficient.
Solution: Water weekly first year, taper off year 2. By year 3, only supplemental water during drought.
Mistake #5: Neglecting Fall/Winter Interest
If your xeriscape is bare and brown October–March, rethink your plant mix.
Solution: Include evergreens (junipers, some salvias) and plants with interesting winter structure (grasses, bare branching shrubs).
Frequently Asked Questions
Q: Can I use native Colorado plants from other regions?
Some high-altitude natives from Wyoming or Utah work fine. Mountain natives (7,000+ feet) appreciate the altitude similarity. Plains natives from eastern Colorado definitely work. Test first if uncertain.
Q: How big do these plants get? Can I control size?
Yes — most respond well to pruning. Serviceberry, Chokecherry, and Rabbitbrush respond well. Grasses can be cut back. Salvias and Catmint can be deadheaded. But it’s easier to plant for mature size than fight growth.
Q: What if I want flowers all season?
Layer perennials by bloom time: spring bloomers, summer bloomers, fall bloomers. Mix shrubs for structure with perennials for color. Reference the Season-Long Color Strategy section above.
Q: Are these plants expensive?
No. Young plants run $8–$25. For a 2,000 sq ft xeriscape, expect $2,000–$4,000 in plant material. Much of the total xeriscape cost goes to hardscape and labor, not plants.
Q: Do I need to fertilize native plants?
No. They evolved on poor Colorado soil. Fertilizer actually makes them weaker and more water-dependent. Let them grow lean and tough.
Q: Which plants attract pollinators?
Salvias, Catmint, Blanket Flower, Rabbitbrush, Lupines, Yarrow, Sedum. Plant these if you want butterflies and bees.
Q: Which plants are deer-resistant?
Most natives are somewhat deer-resistant due to thick foliage or taste. Catmint, Yarrow, and Salvias are especially resistant. Chokecherry and Serviceberry get browsed but survive.
Your Native Plant Xeriscaping Checklist
Before planting, make sure you have:
• Site assessment complete: Sun hours mapped, soil tested, drainage evaluated
• Plant list finalized: Choose 5–8 varieties for diversity (shrubs, grasses, perennials)
• Season-long color planned: Something blooming or interesting spring through winter
• Space planned for mature size: Don’t overcrowd
• Soil prepared: Amend clay with compost or perlite
• Irrigation plan: Hand-water or drip system for first 2 years
• Mulch ready: 2–3 inches of wood mulch to retain moisture and suppress weeds
Get Your Plants from the Right Sources
Don’t just buy from big-box stores. Denver native plant nurseries specialize in plants proven to thrive here.
Top Denver native plant sources:
• High Country Gardens (online, Colorado-based)
• Local native plant nurseries (search “Denver native plants”)
• Colorado State Extension programs (educational resources and recommendations)
What to ask: “Will this thrive at Denver’s altitude?” “Does this handle heavy clay?” “How much water does it need once established?”
Ready to Design Your Native Plant Xeriscape?
