Liriope Plants are hardy perennials that reach a height of 30 to 45 cm. The most commonly grown species of this genus in the garden are Liriope muscari, better known as the Big Blue Lilyturf, and the more aggressive growing and faster spreading Liriope spicata (Creeping Lilyturf).
Liriope muscarii by M. Martin Vicente.
These can be identified from their root system, with Big Blue Lilytuf having fibrous roots, and Creeping Lilyturf having a creeping rootstalk (Rhizomous) system.
They have grass like leaves and spiky purple or white flowers that bloom from late summer until early autumn.
Liriope makes a great edging plant and can also be used in borders.
The small height of this deer resistant plant makes it great to grow as a short ground cover. Ideally grow alongside ornamental grasses.
One of the more common names for the Liriope plant is Lily-turf.

Lily turf and other Liriope Plants should be sown at a depth of about 6 mm (1/4 inch) either at the end of autumn or just before the last frost spring.
Liriope likes to grow in a partially shaded part of the garden that has a moist and fertile soil with good drainage.
If starting off Lily turf and other Liriope indoors then start to grow about 7 or 8 weeks before they are due to be transplanted.
The seeds should first be soaked in warm water for a day and germinated st 18 to 21 degrees Celsius (64 to 70°F); this should take about a month.
Once established, transplant Liriope seedlings into the garden after the last frost of spring about 30 to 40 cm (12 to 16 inches) apart.
Liriope are fairly easy plants to look after. Water regularly in dry periods to keep the ground moist for best results.
After flowering has occurred, remove the flowering stems before the seed has chance to set. This will help prevent Lily turf from spreading in the garden.
In the winter dead leaves should be removed from the plant, and Liriope cut back to about 10 cm (4 inches) in height.
