Mondo Grass
Ophiopogon japonicus 

USDA Plant Hardiness Zones: 5a-10b  Find Your Zone

Note:  For our customers who live and garden north of USDA Hardiness Zone 5a, where this Mondo Grass variety is not reliably winter hardy, you'll be happy to know it can be grown in containers that can be brought indoors during winter and placed back outside when temperatures warm up in spring. 

Special Attributes

A first-class ground cover, Mondo Grass forms a lush mound or carpet of very dark green grass-like foliage. It is similar in appearance to Liriope but with much thinner blades that provide a softer texture. Short spikes of lilac flowers are nestled in the foliage and, for the most part, are inconspicuous. 

Landscape & Garden Uses

Growing about a foot tall and wide (wider over time), Mondo Grass is ideal for use in mass plantings as a groundcover in shady to partially shaded landscape borders and home foundation plantings. Perfect for use as an underplanting for small trees such as Japanese maples or a groundcover under large shade trees. Also serves nicely as a solo or grassy accent in combination container gardens. A fine addition to Asian gardens, rock gardens, and nestled between boulders around the garden pond. 

Suggested Spacing:  4-6" for quick fill;  8-12" if you have patience;  24" for space between mounds

Cultural Preferences

Mondo Grass is very easy to grow in most any moist but well-drained soil of average fertility and part shade to full shade. Morning sun is okay but foliage may fade to a lighter shade of green in direct afternoon sun. Filtered all day sun is okay. Constantly soggy or wet soils can be problematic, though temporary flooding is okay.
