Lilyturf

Lilyturf is a common name for several evergreen perennial plants used as ornamental ground cover. It most often refers to species in the genera Liriope (commonly called lilyturf or monkey grass) and Ophiopogon (often called mondo grass). The two groups are similar in appearance, with grass-like, arching leaves and seasonal flower spikes, but differ in size and flower timing.

Liriope species such as Liriope spicata and Liriope muscari form clumps of broad, strap-shaped leaves, with slender flower spikes bearing small purple-to-lavender flowers in late summer. Ophiopogon japonicus has narrower leaves and small white flowers in spring, followed by dark berries in some cultivars.

Cultivation and use: Lilyturf tolerates a range of soils and light conditions, from full sun to light shade, though most perform best with some afternoon shade in hot climates. It is generally drought-tolerant once established and spreads by rhizomes to form dense mats. It is widely used as ground cover, in borders, under trees, and in containers. In favorable conditions it can spread aggressively.

Care and maintenance: In temperate areas, cut back old growth in spring and divide crowded clumps every few years to maintain vigor. Remove spent flower stalks to reduce reseeding or spread. Most forms are hardy across a broad span of climates, with hardiness varying by species and cultivar.

Notes: The name lilyturf can cause confusion with mondo grass. Botanically, Liriope and Ophiopogon are distinct genera. For garden planning, check the botanical name to select the desired growth habit, flower color, and hardiness.
