Permaculture uses
Mondo grass is primarily used as a ground cover or edging plant in permaculture gardens. It requires minimal maintenance and helps to suppress weeds. While not typically eaten, some cultivars may have edible rhizomes, but palatability varies. It provides habitat for beneficial insects and can help prevent soil erosion on slopes.
Permapeople description
Ophiopogon japonicus, commonly known as mondo grass, is a species of flowering plant in the family Asparagaceae. It is native to Japan.
Botanical description
Ophiopogon japonicus is a grass-like perennial plant belonging to the Asparagaceae family. It forms dense clumps of narrow, arching, dark green leaves, typically 8-12 inches long. It produces small, bell-shaped, pale lilac or white flowers in summer, followed by bluish-black berries. The plant spreads slowly by rhizomes, forming a dense mat. It is evergreen in warmer climates. It prefers moist, well-drained soil and partial shade.
Companion planting
Mondo grass pairs well with shade-loving plants such as hostas, ferns, and astilbes. Its dense growth habit can help suppress weeds around these plants. There are no known significant unfavorable associations.
Propagation methods
Propagation is typically achieved through division of established clumps in spring or fall. Seeds can also be sown, but germination can be slow and uneven. Rooted offsets can also be carefully separated and transplanted.
History and traditions
In traditional Chinese medicine, the tuberous roots of Ophiopogon japonicus, known as 'Mai Men Dong', are used for their purported cooling and moisturizing properties. They are believed to nourish the yin, clear heat, and moisten the lungs. Historically, it has been used to treat dry coughs, thirst, and constipation. In Japan, it is commonly used in traditional gardens and landscaping.
Usage calendar
Flowering occurs in summer (June-August). Division is best done in spring (March-May) or fall (September-November). Planting can be done anytime the ground is workable, but spring and fall are ideal. No pruning is typically required, though dead leaves can be removed in spring.
