Liriope is also called big blue lilyturf, the other common species of Liriope is called creeping lilyturf .Lirope is the first plant I dug from a neighbors yard and transplanted to my garden.
Once this plant starts growing it does not stop. It can be used to edge borders of your flower bed, edge your front yard walkway, and any other spot you need a hardy indestructible plant.
It is hardy in zones five to ten.
Liriope is a hardy evergreen ground cover. Liriope generally grows from ten to eighteen inches tall and is twelve to eighteen inches wide. It grows in clumps with dark green vegetation. Some varieties are variegated. Liriope blooms in July and August with spikes of purple, lavender, or white flowers. The flowers are small but there are a lot of them, making the plant very showy when blooming.
Liriope will grow in anything from full shade to deep shade. For the most flowers, however, plant in full sun. It is a very hardy ground cover and spreads rapidly. Liriope is useful on slopes or banks, under trees, and as edging for flower beds.
Liriope is easy to plant by dividing the root mass of existing plants or through transplants purchased from nurseries. Since this is so much easier than using seed, it is the usual manner of establishing Liriope in the garden.
To plant Liriope, first till up the flower bed to a depth of six inches and add three inches of compost. Then dig a hole slightly larger than the root ball of the Liriope. Carefully remove the plant from the pot and put it in the hole. Firm soil around the roots and plant. Carefully water the plant in. Plants should be spaced one foot apart when planted. They will quickly spread and fill in the spaces between them.
Liriope should be watered one inch of water a week to promote deep roots. Do not let Liriope dry out, but do not keep the soil too wet or the roots will rot. The soil should be moist but not squishy.
Liriope must be pruned in late winter before the spring growth begins. The easiest way to do this is with a mower set at the highest setting. Just mow the plants, being careful not to damage the crowns while doing so. Be sure to remove the mowed leaves and compost them. Leaving them on the plants can spread diseases.
Liriope is fairly tough but is vulnerable to root rot, anacthrose, and snails and slugs. For snails and slugs, spread iron phosphate bait around the plants. It is sold under the names Sluggo and Escar-go. It is not as poisonous to other animals as the old copper based bait. Liriope is considered rabbit and deer resistant.
