Welcome to Vegas! Some plants we use a lot of are all the sage types (green Texas sage, and the many like it), many clump grasses, deer grass, yellow iris grass, and if you have some space, pampas grass gets big and makes nice cover. There's a cute little one called "Hot Lips Sage" that I like as well as chaparral sage (both at Star Nursery, I'm not sure of their scientific names). We use a lot of globe mallow which grows naturally around town at about 3,000' elevation up to 5,000' or so, or you can buy it at Star Nursery occasionally. Mulberry is a great food source but isn't legal to sell/plant in Clark County any more. There's trees all over town if you know what to look for, or you can run over to Pahrump and buy it (different county). They are massive trees eventually, so I wouldn't plant one unless you had space for it to go wild. Spineless prickly pear works well here, sometimes dies off in the winter depending where you live. We are in the far Northwest and it gets a little hotter in the summer and colder in the winter up here, but if it's planted on the South side of a North property block wall, it helps regulate temperature a lot (cold is the biggest problem for it).
