Black Mondo Grass (Ophiopogon planiscapus ‘Nigrescens’) is a striking ornamental plant known for its unique, deep purple to black, strap-like foliage that forms low, arching clumps. Though commonly referred to as a grass, it is technically a member of the Asparagaceae family and functions like a ground-hugging ornamental shrub or grass in landscape design.

Native to Japan, it naturally grows in shaded forest edges and rocky slopes. Its slow-growing, compact habit and dramatic coloring make it a popular choice for edging, groundcovers, or contrast planting in modern and traditional gardens alike. In summer, it produces delicate, pale lilac or pink bell-shaped flowers, followed by glossy black berries that add further visual interest.

Black Mondo Grass is prized for its unusual coloration, year-round appeal, and ability to create bold visual contrast against green foliage or light-colored paving. It’s a favorite in contemporary designs and Asian-inspired gardens for its minimalist elegance and sculptural form.
