In Utah, the most commonly-used type of grass is Kentucky bluegrass. Unfortunately, it also uses more water than any other turfgrass species. Other options that will do well in Utah's climate but use less water are Tall fescue, the fine leaf fescues, Buffalograss, Blue grama, and Crested wheatgrass. Tall fescue uses from 10 to 30% less water than Kentucky bluegrass and fine leaf fescues use slightly less than that. Buffalograss and Blue grama grass use approximately 50% less water than Kentucky bluegrass. Crested wheatgrass can actually survive without any supplemental irrigation once it's established.
