  This small, easy to grow, clump-forming evergreen perennial has strappy, inky purple, grass-like leaves. In summer, small spikes of bell-shaped, pale mauve flowers appear, followed by spherical, dark blue fruit. This unusual plant looks fantastic with other grasses, especially if grouped in tubs or planted into gravel, and it provides a brilliant contrast with silvery plants in sun, or bright green ferns in shade.
