An Unassuming Evergreen
Liriope, commonly called lilyturf, is a tough evergreen perennial with grass-like leaves that is easy to mistake for a grass at first glance. It earns its keep at the front of shady borders and as ground cover, then surprises in early autumn with spikes of small purple or white flowers.

A Nymph's Namesake
The genus takes its name from Liriope, a woodland nymph of Greek myth and mother to Narcissus. Liriope muscari, the most widely grown species, comes originally from East Asia.

Light for Flower, Not Just Leaf
Liriope is untroubled by most soils, including drier ground, and tolerates drought once established, though it does best in moist, well-drained conditions in partial or full shade. It needs some direct sun for part of the day to flower well, as plants kept in deep shade tend to stay leafy but shy of bloom. Established clumps rarely need routine watering except in a very dry summer or when grown in full sun, and a general fertiliser in spring can help a struggling patch, though mulching to retain moisture is often the more useful fix.

Division Over Seed
The easiest route is dividing clumps in spring, and gardeners need not be alarmed by the white tuber-like lumps found among the fibrous roots when doing so. Growing from seed extracted from the berries is possible in spring at around 10°C, but it is more of a curiosity than a practical method, since named cultivars will not come true from seed.

Grass-Like Clumps and Berries
Liriope muscari forms dense clumps of arching, leathery dark green leaves reaching some 25-45cm, while Liriope spicata spreads more loosely and suits ground cover in shadier corners. In autumn, upright drumstick-like spikes carry small violet-purple or white flowers, followed by black or dark purple berries that are worth leaving in place rather than trimming away. Some cultivars bring extra interest through the foliage itself, with white or yellow leaf stripes, and one, Okina, unfurls new leaves almost pure white before they green up.

Slugs, Mostly
Liriope is largely trouble-free, generally free of disease, with slugs noted as the main pest to watch for.

Dry Soil, Deep Shade
Poor growth in liriope usually traces back to overly dry soil, which mulching with organic matter and watering through dry spells will help correct. A lack of flowers points to too much shade, so pruning back overhanging growth or moving plants somewhere they catch sun for part of the day should encourage blooming again.

Tidy in Spring
Remove dead or damaged leaves by hand each spring, and if a clump of Liriope muscari has grown untidy over the years, it can be cut hard back then to rejuvenate it. Liriope spicata's finer foliage often takes winter damage and benefits from an annual spring shearing. Leave the old flower spikes on the plant through winter for their berries, and clear them away only when tidying the clump in spring.
