Water needs: Medium- to low-water; once established, water deeply once a week or twice a month.
Snapshot: This Idaho native adds interesting color and movement to the water-wise garden. A fine-textured grass with attractive powder-blue foliage, Clearwater fescue looks like a cool blue pool planted en masse or can be mixed as contrast with bold, dark green foliage plants. Its silvery flower stalks rise from foliage in spring and summer and float like feathers in the Delta breeze. More compact than similar fescues, Clearwater makes an attractive accent plant in small spaces, too.
