Black mondo grass (Ophiopogon planiscapus ‘nigrescens’)

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.
