Once established, the right ornamental grass can go weeks without supplemental water and still hold its color and structure — no other plant category does drought tolerance quite as well. The catch is that "drought tolerant" almost always means after an establishment period, not from the day you plant it. Get the timing right and these are some of the lowest-maintenance, lowest-water plants you can put in the ground.
Our Top Picks for Low-Water Landscapes
Muhlenbergia rigens — Deer Grass
A California native that handles genuinely dry conditions once established, with the bonus of being deer resistant too. Its fountain-like mounded habit works equally well as a single specimen or massed for a low-water meadow look.
Shop Deer GrassFestuca idahoensis — Idaho Fescue
A fine-bladed, blue-green native bunchgrass built for exactly the kind of dry, open conditions found across much of the West. Compact enough for borders, tough enough for a true xeriscape planting.
Shop Idaho FescueBouteloua gracilis — Blue Grama Grass
A true prairie native built for low water from the ground up — Blue Grama survives on rainfall alone across some of the driest grassland in North America. Distinctive curled seed heads give it real textural interest beyond just being tough.
Shop Blue Grama GrassSesleria autumnalis — Autumn Moor Grass
Bright chartreuse-green foliage that holds its color through summer heat with minimal water, then shifts to a warm tan in fall. A versatile, well-behaved low-water grass that works as a ground cover or border edge.
Shop Moor GrassCalamagrostis x acutiflora 'Karl Foerster'
Proof that low-water doesn't mean low-impact. Once established, 'Karl Foerster' tolerates real drought stress while still delivering the rigid, upright structure it's known for — making it one of the few low-water grasses that also works as a privacy or specimen planting.
Shop Feather Reed GrassDesigning a Low-Water Bed
Group plants with similar water needs together rather than mixing low-water grasses into a bed with thirstier plants — this lets you actually cut back on irrigation rather than watering the whole bed for the sake of one needy plant. Gravel or decomposed granite mulch (rather than bark) also helps low-water plantings specifically, since it reflects heat away from the crown and doesn't hold the kind of moisture that can rot drought-adapted roots.
Pair With Native Plantings
Several of the grasses above are also true California or Western US natives, which means they're doing double duty — low water and genuinely adapted to the regional ecosystem.
