Dwarf Mondo Grass ‘Nana’ or ‘Nanus’
This dwarf variety is only half the size of the species. Excellent as an edging plant or tucked into rocks for a pleasing contrast. Creates a lush groundcover of dense, dark green grass-like clumps.
In the Garden
Dwarf mondo grass has a clumping growth habit. Dark green, grass-like leaves grow slowly, but once established make an excellent ground cover, border planting or accent to rock gardens.
- Reaches only 3 to 4 inches tall
- Slow growing.
Caring & Growing
USDA Hardiness Zone: 6 – 11
Suitable from full sun to full shade.
Mondo grass prefer loose, loamy soil. The plants will tolerate clay soil, but will have difficulty spreading their roots through heavy sod. If the roots can’t spread, your mondo grass will be unable to cover an area to create a dense ground cover. Sandy soils will not retain the water or provide the nutrients mondo grass requires. If you have clay or sandy soil, amend the area with compost or potting soil to a depth of 10 to 12 inches before planting mondo grass.
Follow a regular watering schedule, usually every 10 to 14 days, wet the area thoroughly so the water penetrates deep into the soil. Placing a 2-inch layer of mulch around the plants will help retain soil moisture and reduce the frequency of watering. The soil moisture level should remain consistent and not allowed to dry out, and never allow it to become soggy. Stop applying water during the winter when new growth has slowed or stopped.
During the growing season, fertilize dwarf mondo grass every three months using balanced, slow-release fertilizer. Apply the fertilizer at a rate of 1 tablespoon per 1 square foot of ground. Broadcast the fertilizer in a band around the plants. Mix the fertilizer granules into the top 1 to 3 inches of soil with a rake. Water the area thoroughly.
