Outdoors Black Mondo Grass is slow growing but it is tough and tolerates shade.
It does best in filtered light, although it can tolerate partial shade and even direct sunlight.
Water
Mondo grass does best with regular, even water, but it is somewhat drought-tolerant and can handle periods of extended dryness.
Temperature
Room temperature is good. Mondo grass is not particular in regards to the temperatures, but cannot withstand freezing.
