Building Structure: Layers That Do the Work
A durable xeriscape is built in layers, the same way a natural plant community is. Each structural layer earns its place, and together they give the planting year-round presence while keeping water demand low.
- Trees set the ceiling and provide shade that cools everything beneath. Low-water choices: bur oak and hackberry for large shade on the plains, pinyon pine for evergreen structure, desert willow and palo verde for warm-climate accent bloom.
- Shrubs are the backbone — mass, screening, and off-season structure. Rabbitbrush (electric-gold fall bloom), three-leaf sumac (fall color, berries), fernbush, apache plume, big sagebrush (silver evergreen anchor).
- Perennials carry color and pollinator value: penstemon, salvia, agastache, yarrow, blanket flower, Russian sage, coneflower, catmint.
- Grasses add movement, texture, and winter interest: blue grama (Colorado's native state grass, also a lawn alternative), little bluestem, prairie dropseed, blue oat grass, and taller switchgrass.
- Groundcovers replace mulch and turf, cover soil, and cut evaporation: hardy ice plant, sulphur buckwheat, creeping veronica, and manzanita.
Design with all five layers and the planting reads as intentional and complete, not as scattered specimens in a sea of rock.
