Ophiopogon umbraticola (National Arboretum Mondo Grass) - A dense evergreen, low-growing slowly spreading fine textured grass-like plant 4 to 6 inches tall with 6 to 10 inch long dark green very narrow (1/8") leaves are erect and then bend over. The small mauve tinged white flowers in small clusters along a short inflorescence in summer are followed by large blue berries in fall which are attractive when found hidden under the foliage. It is slowly spreading via short rhizomes so acts more like a clumping plant than one such as Ophiopogon clarkia that spreads around with a more open habit. Grows in full or part coastal sun to light shade with regular to occasional watering. This plant is quite hardy and can be used where other Ophiopogon might freeze (below 0F) and useful in zones USDA 7-10. This plant comes from China (Northern Guangdong, Northeast Guizhou, Jiangxi, Southeast Sichuan) where it grows in forest and among scrubs along cliffs and streamsides in moist and shady places areas from 2,300 to 3,300 feet. This plant is much finer textured than the typical Ophiopogon japonicus sold in the trade and there both the solid green form and a variegated form. It originated from plants at the United States National Arboretum in Washington, DC where it was originally accessioned incorrectly as Ophiopogon chingii, a valid name for a stoloniferous plant with much wider leaves (3/4 inch wide) that also comes from China. It has also been sold as Ophiopogon graminifolius, a name considered synonymous with Liriope graminifolius . Our thanks go out to Richard Abe for our stock plants and to John Greenlee and Tony Avent for their help to sort out the proper name for this plant.
The information on this page is based on research conducted in our nursery library and from online sources as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens that we have visited. We have also incorporated comments received from others and always appreciate getting feedback of any kind from those who have some additional information, particularly if this information is contrary to what we have written or includes additional cultural tips that would aid others in growing Ophiopogon umbraticola.
