Dwarf mondo grass is a miniature version of regular mondo grass that reaches a height of only about 2 to 4 inches. This ornamental plant will spread out to form a thick layer of grassy turf that is resistant to drought and pests and never needs to be mowed. As a member of the lily family, dwarf mondo does not have the thirst for water that ordinary grass has. The plants have even been known to maintain their green color during periods of drought-like conditions. Dwarf mondo grass grows well under shady or sunny conditions. Many landscapers like to use this plant in patches between trees in a shady area because they handle lack of sunlight better than most grasses. It is also frequently used between stepping stones, to mark the border of a garden or pathway, or in flower beds.
