Ophiopogen Japonicus Nana, or Dwarf Ophiopogen Japonicus, is a very low-growing, dense variety of Ophiopogen Japonicus. Commonly known as Dwarf Mundo Grass, it is much more compact than the regular variety. This clumping, mat-forming evergreen perennial is a good alternative to turf or lawn. Excellent choice for Japanese gardens or for edging pathways and flower beds.
Native to Asia, this cultivar belongs to the family of evergreen perennials grown for their highly-decorative foliage. Dwarf Mundo Grass has grass-like, arching, leathery leaves that keep their dark green colour year-round. Although highly prized, the foliage is not the only noteworthy quality of this dwarf grass. In late summer, spikes of dainty lilac blossoms appear, which are followed by glossy, blue-black berries that beautifully contrast with the evergreen leaves.
Tough and undemanding, Dwarf Ophiopogen Japonicus needs very little to thrive. This dwarf grass will appreciate a well-drained, humus-rich soil in full sun or partial shade, and can adapt to both exposed and sheltered locations. Pest and disease free, Dwarf Mundo Grass is easy to grow and to care for. No pruning is required to keep the mat-forming habit of the plant in check, as it is not considered invasive and forms an attractive mound naturally.
Depending on the area, Ophiopogen Japonicus Nana can keep its glossy, green foliage during the winter months. Fully hardy in Britain, this cultivar is mostly evergreen, but in areas where temperatures get particularly low during winter, the foliage may drop.
Half the size of its close relatives, Dwarf Ophiopogen Japonicus will achieve a maximum size of 10 centimetres in width and height. Even though petite in size, this cultivar flaunts a dense, lush foliage that is strong enough to walk on. However, considering that the specimens are tiny even when fully mature, approximately 150 plants are needed to cover a square meter.
Robustness of the attractive foliage, as well as its mat-forming habit, make Ophiopogen Japonicus Nana ideally suited to be grown as a ground cover on bare patches of land, or as an evergreen alternative to lawn or turf. The grass-like leaves offer texture and colour throughout the year, so consider using this cultivar for edging pathways or flower beds and borders.
