What it means
Xeriscape is the formal word for the yard most Scottsdale houses already have: gravel instead of lawn, a drip line under it, palo verde and mesquite for shade, and a set of shrubs you could not name on the day you moved in. It means landscaping built to need little or no extra water, and it is pronounced ZEER-uh-scape, from the Greek xeros, dry. Say “zeroscape” and a landscaper will know what you mean and quietly correct you, because the mishearing has come to describe the one thing xeriscape is not: a bare lot of rock.
Locals use the word less than you would expect. The city’s water department says “Arizona-friendly” or “desert landscaping” and reserves “Xeriscape” for the demonstration garden it built at Chaparral Park; HOAs say “approved plant list”; nurseries say “low-water.” But the idea runs through everything about living here, from the first-year note’s warning that lawns are a choice most new neighborhoods will not let you make, to the moving guide’s line that water is priced to discourage grass.
Where you’ll meet it
At the Scottsdale Xeriscape Garden, six free acres on a buried reservoir at 8111 E. McDonald Drive. On the rebate page at Scottsdale Water. In the HOA’s landscape guidelines. And on the day you pull the first clump of Bermuda and hit caliche.
Where the word came from
The word is Denver’s. In 1981 Nancy Leavitt, an environmental planner at Denver Water, needed a name for a water-conservation campaign that would not sound like deprivation, and joined the Greek root for dry to “landscape.” Denver Water promoted the term across the West through the 1980s with a set of principles, planning, soil, limited turf, efficient irrigation, mulch, suitable plants and maintenance, that every Southwestern water agency eventually adapted. The word spread faster than the idea: by the 1990s it was on nursery signs from Albuquerque to Las Vegas, and so was its evil twin. “Zeroscape,” rock from wall to wall with a single sad agave, became the shorthand for a yard that saves water by growing nothing, and the two were so often confused that Denver Water renamed its own program ColoradoScape in 2023 to escape it.
Scottsdale came at the practice from the other direction. The Sonoran Desert had been landscaping itself for a few million years, and the city’s older neighborhoods simply kept the natives when the subdivisions went in. What the word gave Scottsdale was a program. Scottsdale Water began paying rebates for low-water fixtures and landscapes in the early 1990s, and in 2008 opened the Xeriscape Garden on top of the Chaparral treatment plant’s reservoir, more than 7,000 plants of about 200 species, each bed signed with the water-wise principle it demonstrates. The name on the gate is the one place the city uses the word without hedging.
What it is not
Xeriscape is not gravel, and it is not cactus-only. A yard of decomposed granite with no canopy is hotter than a lawn, radiates into the house all evening and is the thing the word was invented to prevent. The desert plants field guide is the corrective: trees first, then shrubs, then the rock.
The fine print
The money is where the word gets teeth. Scottsdale Water’s residential grass removal rebate pays $2 per square foot of living turf removed and replaced with approved desert-friendly landscape, up to $5,000 per property, on a minimum of 500 square feet. The city doubled the rate from $1 in 2023, and participation jumped 450 percent; in fiscal 2023 residents took out more than 401,000 square feet of grass, which the city calculates will save more than 20 million gallons a year. A $250,000 grant from the state’s Water Infrastructure Finance Authority, approved September 20, 2023, helped cover the demand. The rules are strict about order: apply, get a pre-inspection and a notice to proceed, then dig. Grass already gone is ineligible, and the pot runs first-come, first-served until the deadline or the money is exhausted. Companion rebates cover smart irrigation controllers (up to $250), home water monitors ($100) and, for the committed, removing a pool ($1,500).
The arithmetic the city uses to sell it: roughly 70 percent of a Scottsdale home’s water goes outdoors, mostly to turf, and winter overseeding alone takes about 8,000 gallons a season for every 1,000 square feet of rye. Against that, a mature mesquite on a drip line is nearly free.
The Scottsdale Water guide explains why the city cares: about 90 percent of its supply is river water, two-thirds of it Colorado River through the CAP canal, and the Colorado is the one running short. Xeriscape, by whatever name the city uses this year, is the cheapest water Scottsdale can buy. The HOA is the other half of the story; most north Scottsdale CC&Rs now require desert landscaping in front yards, which means the rebate’s remaining customers are the older lawns of the south and the flood-irrigated blocks that have the cheapest water of all.
