Ophiopogon japonicus ‘Nana’, commonly known as dwarf mondo grass, is a miniature, slow-growing cultivar of Ophiopogon japonicus noted for its fine, tufted, grass-like foliage. This evergreen perennial forms dense clumps and is one of the smallest mondo grass varieties. It bears small pale lilac to white flowers in summer, followed by blue-black berries. Ophiopogon japonicus ‘Nana’ is widely used as a groundcover, edging plant, or between stepping stones, and is valued for its low maintenance, year-round foliage, and ability to create a lush, moss-like effect in landscape designs.
