Ophiopogon japonicus 'Nana'Dwarf Mondo Grass

The Ophiopogon japonicus ‘Nana’, or Dwarf Mondo Grass, is a low-growing, clump-forming evergreen groundcover admired for its fine, dark green, grass-like foliage. Growing to just 5–10 cm tall and slowly spreading up to 20–30 cm wide, this hardy plant is ideal for borders, between pavers, or as a dense, weed-suppressing groundcover. In summer, it produces small, lavender to pale purple flowers, followed by ornamental black berries.

Low-maintenance and versatile, Dwarf Mondo Grass thrives in shaded areas, adding texture and lush greenery to gardens and landscapes.
