Ophiopogon japonicus

Ophiopogon japonicus, Mondo Grass or Dragon Beard, is native to China, India, Vietnam and Japan. It is an evergreen perennial of the Asparagaceae family which spreads by rhizomes and stolons. In their natural habitat they are often found along streams or in moderate damp woodland conditions where they thrive in shade to semi-shade. Flowers are quite insignificant but the berries are a beautiful pearly blue.

In their native Japan Ophiopogon are used around water basins or rocks for accentuation and to soften their base. The smaller cultivars like ‘Kyoto’ and ‘Tama-ryu’ are often planted between stones in a path or along gravel garden edges to imitate moss. They are also sometimes used as underplanting for larger bonsai.

Ophiopogon are not prone to have many pests or diseases but vine weevil, especially when the plants are grown in pots, need to be treated with nematodes.


Propagation of Ophiopogon is very easy. Rooted stolons can be split off and potted up to increase stock. Some Ophiopogon however are very slow growing so it may take some time before the plant is big enough to be split.
