Crested hairgrass is a tough, low-maintenance ornamental grass that thrives in full sun to partial shade with average moisture. It forms attractive silvery-green tufts and tolerates poor soils, making it ideal for naturalistic gardens or meadow plantings. Water occasionally during dry spells and divide clumps every few years to keep the plant vigorous.
