What is the difference between Japanese dwarf mondo grass and Ophiopogon japonicus 'Nanus'?

Japanese dwarf mondo grass and Ophiopogon japonicus 'Nanus' are the same thing. The Japanese dwarf mondo grass plant is low-growing, with a height of around 5-10 cm, and it is most often used as a lawn. Japanese dwarf mondo grass is sold by weight, generally 5-6 yuan per jin.

In a shaded environment, the leaves of dwarf mondo grass are emerald green, and when planted in the ground it should be in a shady spot and under trees. Potted plants are best placed under a shade canopy to avoid direct sunlight. Dwarf mondo grass is quite cold-hardy and can overwinter outdoors in southern regions, but in the north it should be moved indoors in winter, with the temperature kept above 5°C and never below 1°C. Although low temperatures will not freeze the roots, the leaves will turn yellow.

Points to note when planting

(1) In the first and second years after planting, removing weeds is the main task;

(2) Weeding must be timely, because dwarf mondo grass is short and can easily be covered by weeds, seriously affecting its growth;

(3) When weeding, remove the roots. Using a weed-whacking machine to clear weeds is not recommended, because mechanical weeding cannot remove the grass roots, and in a short time the weeds will run wild again. Trimming the tips of dwarf mondo grass is not recommended either; the height difference between dwarf mondo grass plants is already very small, so why bother trimming and leveling them
