Ophiopogon japonicus ‘Nana’ (Dwarf Mondo Grass)
Ophiopogon ‘Nana’, commonly known as Dwarf Mondo Grass, is a very low-growing, evergreen groundcover valued for its fine, dense foliage and compact form. It is widely used in detailed landscape work such as between pavers, edging, and small-scale groundcover where a tight, uniform finish is required.
The plant produces extremely fine, narrow leaves in deep green tones, forming dense, cushion-like clumps. Its miniature size creates a soft, carpet-like effect that is highly suited to formal and intricate garden designs.
