Native Grasses for Low-Water Colorado Lawns
A native grass lawn runs on a fraction of bluegrass water — if you accept a different look and rhythm. Here are the three species that work and the tradeoffs in plain terms.

The Deal You're Making
A native grass lawn is a genuine option on the Front Range, not a compromise — but it's a different product than bluegrass, and conversions go best when that's understood up front. You're trading the deep-green carpet look and long green season for a soft prairie turf that lives on rainfall in a normal year, needs mowing a handful of times per summer, and asks almost nothing else.
The three species that do the work:
Buffalograss
Bouteloua dactyloides
- Height
- 4–8 inches unmowed
- Width
- Spreads by stolons
- Sun
- Full sun
- Water
- Very low
- Bloom
- Warm-season turf
The only native that behaves like a true lawn grass — it spreads by surface runners into a soft, gray-green, walkable turf. Established buffalograss survives on precipitation in a typical year and tolerates kids and dogs better than its delicate look suggests.
It wants full sun and goes golden-dormant from October to May. That dormant color is the tradeoff to make peace with before converting.
Blue Grama
Bouteloua gracilis
- Height
- 6–12 inches unmowed
- Width
- Bunch-forming
- Sun
- Full sun
- Water
- Very low
- Bloom
- Summer, eyelash seed heads
Colorado's state grass, instantly recognizable by seed heads that hang like eyelashes. Mixed with buffalograss it fills a lawn out and speeds establishment; left unmowed it reads as a soft meadow rather than turf.
It's a bunchgrass, so blends lean on buffalograss for the knit and blue grama for density and quick cover.
Little Bluestem
Schizachyrium scoparium
- Height
- 18–36 inches
- Width
- 12–18 inch clumps
- Sun
- Full sun
- Water
- Very low
- Bloom
- Ornamental, coppery fall color
Not a mowing lawn — little bluestem is the accent and edge grass for native lawn projects: blue-green columns all summer, glowing copper-red through fall and winter. Use it in drifts along borders and slopes where the lawn transitions to beds.
It asks for nothing but sun and drainage, and it's at its best left standing all winter.
Native Lawn vs. Bluegrass, Honestly
| Factor | Buffalograss/blue grama lawn | Kentucky bluegrass lawn |
|---|---|---|
| Summer water | 0–1 soakings per month, most years | 2–3 waterings per week |
| Green season | Mid-May to early October | April to November |
| Mowing | Optional; a few times per season | Weekly |
| Look | Soft, fine, gray-green prairie turf | Dense, dark, uniform carpet |
| Traffic | Good once established | Excellent, self-repairing |
| Shade | Poor — full sun only | Poor to fair |
| Establishment | 1–2 seasons of patience, real weed pressure | Fast from sod |
| Fertilizer | Little to none | Regular program |
Establishment Is the Whole Project
Native lawns are cheap to run and demanding to start. Warm-season seed wants soil above 60°F — late May through June seeding, not the fall window used for bluegrass and fescue. The first season is a weed fight: everything in the soil bank germinates alongside your grama, and the natives are slower out of the gate. Plan on a full season of patience, spot-weeding, and light establishment irrigation, and a second season for the turf to close ranks. Buffalograss plugs or sod shortcut the ugly year where budget allows.
