Cymophyllus fraserianus

This is essentially a showy-flowered evergreen sedge. Rarely available, it's one of the most desirable shade-loving perennials for eastern U.S. gardens. The bottlebrush spikes of white flowers appear in spring, accompanies by a new complement of strappy dark-green leaves. Wonderful. Zone 5. Propagated from divisions. Deep 3.5-inch pots.
