Xeriscaping Basics for Colorado Yards
Xeriscape was invented in Denver and it doesn't mean zero plants. Here's the real framework — hydrozones, soil, and the right plants — and the mistakes that give it a bad name.

Xeriscape Is a Denver Word — and It Doesn't Mean Gravel
The term was coined by Denver Water in 1981: xeros (dry) plus landscape. It describes designing a yard around the water that actually falls here, instead of importing a Midwest lawn and irrigating it into existence. What it does not mean is scraping the yard and dumping rock — that's "zeroscaping," and it's what gives the idea a bad name: a heat-radiating gravel lot with three sad junipers.
A real xeriscape is usually more planted than what it replaces — just planted with things that belong in a dry climate.
The Framework: Hydrozones
The working idea behind every good xeriscape is grouping plants by water need — hydrozones — so each zone can be irrigated (or not) on its own terms.
| Zone | Water budget | What lives there |
|---|---|---|
| Oasis zone | Regular irrigation | Small kept lawn, vegetable bed, the shade tree — near the house where you use it |
| Transition zone | Occasional deep soaks | Flowering shrubs, tough perennials, ornamental grasses |
| Xeric zone | Rain only after establishment | Natives — penstemon, rabbitbrush, yucca, blue grama — on the edges and slopes |
That's the whole trick. Water problems come from mixing zones — a native drowning next to a lawn head, or a rose bush stranded in the rock. Separate them and every plant gets what it wants.
The Seven Principles, Colorado Edition
- Plan before you dig — decide what stays (that lawn panel the kids use) and what converts.
- Fix the soil where you'll plant; even natives establish faster in clay opened up with compost.
- Keep some turf where turf earns it — a small irrigated panel you use beats a big one you mow.
- Choose plants by zone, and plant in drifts, not polka dots.
- Irrigate by zone: drip for beds, efficient heads for remaining turf, nothing for the xeric edge after year two.
- Mulch everything — wood mulch around plants, rock where you want a crisp, low-litter finish.
- Maintain it — a xeriscape is low maintenance, not no maintenance; weeds love fresh rock beds.
The Mistakes That Give Xeriscape a Bad Name
- Rock over the whole yard with landscape fabric and near-zero plants — hotter in summer, dead year-round
- Rock mulch right up against the house's south side, cooking the foundation plantings
- Skipping establishment water because the plants are "drought tolerant" (they will be — in two years)
- One irrigation zone shared between new natives and old lawn
- Weed fabric under wood mulch beds — it stops soil renewal and the weeds just root in the mulch above it
- Planting one of everything from the nursery's native rack instead of drifts of a few reliable species
For plant choices that carry a xeric bed from spring to frost, start with our lists of bee-friendly plants and native flowering shrubs — nearly everything on both lists fits the transition or xeric zone.
