Mondo grass (Ophiopogon Japonicus and other species) in all of its varieties has been one of the favourite low to medium growing grasses or ground cover plants with landscapers for a number of years.
Although most used widely as a ground cover it is also suited for planting between pavers (see picture right) as well as for use as an edging plant. With its green or black strappy leaves, this is a low maintenance easy care plant.
Loved by landscapers for its ‘low care’ characteristics and the fact that it grows in shade. This is one of the few ornamental grasses that will reach its best height and stop.
This is a strapped leaf plant that is available in the common green form, black as well as a variegated form that is a little more difficult to find.
With a number of varieties available ranging from mini mondo to taller cultivars you can select a height of between 30cm tall to around 10cm.
- Ophiopogon japonicus the common variety. Dark Green Foliage to 10 -15cm
- Ophiopogon japonicus var. nanus a dwarf variety . Dark Green Foliage to 5cm

Mondo Grass Care
This is an ornamental grass that requires little care, although it does not like frost so plant in frost free areas. All varieties prefer a moist but well drained soil and actually do better in part shade than full sun.
Best grown in an open free draining loamy soil which allows easy natural root growth and therefore faster establishment of good sized clumps. Soil does need to be able to retain some moisture, so prepare well by adding some well rotted compost before planting.
Mulch around individual plants and water in with a liquid seaweed fertilizer when planting.
Annual Top dressing of with an organic compost will help promote growth. A slow release fertilizer is best.
Mondo grass works well as an underplanting for small shrubs in containers, it does require a good quality potting mix to thrive.

- Planting Mondo Grass

- Mondo Grass Spacing
Larger growing species can be planted 20 – 30 cm apart. Dwarf Species 7-10 cm apart.
