Utah has limited water resources. There has been a great deal of interest in recent years in planting xeriscaped (low water usage) gardens. Unfortunately, the rush to xeriscaping led many less than scrupulous plant dealers to import a host of invasive weeds into Utah gardens.
In my opinion, the xeriscaped gardening style desigened for Phoenix is not the best style for the high mountain desert. On the edge of the Wasatch Front, Utah Valley has a unique combination of climate zones. The town is at the transition between alpine and high mountain deserts. The best gardens in Provo use native species common from these distinctive climate zone.
If you are planting a flower garden, I strongly recommend the rock garden style from Utah native plants.
