Ophiopogon japonicus (Mondo grass, Fountain plant, monkey grass; Japanese: ryu-no-hige ("dragon's beard") or ja-no-hige ("snake's beard")) is a species of Ophiopogon native to Japan.



It is an evergreen, sod-forming perennial plant. The leaves are linear, 20–40 cm long. The flowers are white to pale lilac, borne in a short raceme on a 5–10 cm stem. The fruit is a blue berry 5 mm diameter.[1]

Medicinal uses

In Chinese medicine Ophiopogon japonicus tuber, known as mai men dong (Chinese: 麥門冬), is the cardinal herb for yin deficiency. According to the Chinese Herbal Medicine Materia Medica, the herb is sweet, slightly bitter and slightly cold, enters the Heart, Lung and Stomach channels and nourishes the yin of the Stomach, Spleen, Heart and Lungs and clears heat and quiets irritability. It is used for hacking dry coughs, dry tongue and mouth and constipation. Liriope spicata is used as a substitute.[2]


It is also grown as an ornamental plant, providing an excellent groundcover. Several cultivars have been selected, including 'Albus' (white flowers), 'Compactus' and 'Kyoto Dwarf' (dwarf forms, not over 4–5 cm tall), and 'Silver Dragon' (variegated, with white-striped leaves). It is often sold as a decorative plant for freshwater aquaria, but because it is not a true aquatic plant, it may flourish for a few months and then die. While hardy to temperatures of about -20 °C when dormant in winter outdoors in normal soil, when kept fully submerged it requires water temperatures of 18-25 °C. It grows well in full sun or partial shade. Propagation is from side shoots.[1][3]
