Ophiopogon is a genus of about 50 species of evergreen, rhizomatous or tufted perennials. They are much appreciated by their dense tufts of grass-like leaves. This habit makes them good choices for ground cover, border edging or rock gardens.
Ophiopogon planiscapus has dark green leaves while the cultivar Ophiopogon planiscapus ‘nigrescens’ (Black mondo grass) has dark black leaves which makes them perfect plants for contrasts in the garden.
In summer they produce pink, white, lilac flowers on leafless stems follower by spherical blue or black fruits.Common name: Black mondo grass

How to plant
Mondo grass should be planted outside in moist but well drained soil. They prefer a slightly acid soil, humus-rich and fertile. Plant in full sun or partial shade positions.
The easiest way to propagate mondo grasses is by division. We wrote a complete guide on how to divide black mondo grass (Ophiopogon planiscapus ‘nigrescens’).
You can also reproduce black mondo grass by seed in spring.
Slugs and snails may damage young leaves.
