Western Idaho blue-eyed grass is a delicate native perennial that thrives in moist, partially shaded meadow conditions. Plant it in organically rich, consistently moist soil and avoid letting it dry out completely between waterings. It is an excellent low-maintenance choice for native wildflower gardens and rain gardens in western states.
