How to grow ophiopogon
Grow healthy, evergreen ophiopogons, with the help of our start-to-finish Grow Guide.
Ophiopogon is also known as lilyturf and mondo grass. It's a grass-like perennial that spreads by rhizomes into a carpet of tufted, narrow, evergreen leaves.
Small, white flowers appear in summer, followed by black berries in autumn, but the foliage is the main feature. The most popular varieties of ophiopogon are the dramatic looking black cultivars. They're a good option for ground cover in a shady spot and are also useful in container displays, and the underplanting of trees and shrubs. The foliage contrasts well with other low-growing perennials or bulbs like cyclamen and snowdrops.

Where to grow ophiopogon
Grow ophiopogon in moist, but well-drained soil. It prefers the slightly acidic, fertile, humus-rich soil typical of shady woodland areas. Choose a spot in full sun or partial shade. The black foliage varieties will darken more in a sunny location.
Although ophiopogon will spread, if you're planting up an area under a tree or in a container, use several plants to get an immediate effect. Add a little leaf mould or a handful of ericaceous compost and mix well before planting, firming in and watering.
Propagate ophiopogon by dividing in spring as the plant comes into growth. Simply dig up and pull apart the plant to create new ones.
