Plant 'Lucerne' in well-draining soil, and then ensure that it stays moist but not overly wet. Larger plants should not be allowed to crowd it out, as Blue-Eyed Grass loves ample sunshine each day. Once bloom time has ended, shear the plant if you desire to keep it in control, or let it go to seed for self-sowing (not vigorous self-sowing in this case). Every few years, divide each clump by separating the rhizomes.
