Liriope muscari
Grass-Like Evergreen Groundcover
- Evergreen Foliage: Provides year-round interest with its attractive, grass-like leaves, even in winter (in most climates).
- Beautiful Blooms: Features showy spikes of purple (or sometimes white, depending on the cultivar) flowers in late summer and early fall, adding a pop of color when many other plants are fading.
- Low Maintenance: Extremely easy to care for once established, requiring minimal watering, fertilizing, or pruning. Drought tolerance.
- Versatile: Works beautifully as a groundcover, border edging, in mass plantings, under trees, or even in containers. Sun and shade.
- Erosion Control: Its dense root system helps to stabilize soil on slopes and prevent erosion.
- Deer and Rabbit Resistant: Generally, not bothered by deer or rabbits, making it a great choice for areas with these pests. (It is important to note the word "resistant," not "proof," as a very hungry animal might nibble.)
- Drought Tolerant: Once established, Liriope muscari is remarkably drought-tolerant, requiring minimal supplemental watering.
- Adaptable to Various Soil Types: While it prefers well-drained soil, it can tolerate a range of soil conditions, including clay.
- Salt Tolerant: Suitable for coastal gardens.
- Botanical Name: Liriope muscari
- Common Names: Lilyturf, Big Blue Lilyturf, Monkey Grass (though technically, "Monkey Grass" often refers to Ophiopogon japonicus)
- Hardiness Zones: Typically, USDA Zones 6-10 (some cultivars may be hardy to Zone 5 with protection).
- Light Requirements: Full sun to partial shade. Flowering is generally best in full sun (at least 6 hours of direct sunlight), but the plant will tolerate shade. In hot climates, afternoon shade is beneficial.
- Soil Preferences: Well-drained soil is preferred. Amend heavy clay soil with compost or other organic matter to improve drainage.
- Mature Size: Typically, 12-18 inches tall and wide (this can vary by cultivar).
- Bloom Time: Late summer to early fall.
- Flower Color Usually purple but can be found in white.
Planting Bare Root Liriope:
- When to Plant: The best time to plant bare root Liriope muscari is in the fall or early spring, while the plant is dormant. This allows the roots to establish before the stress of hot weather.
- Soaking: Before planting, soak the bare roots in water for 1-2 hours (no more than 4 hours). This rehydrates the roots.
- Spacing: Space plants 12-18 inches apart, depending on the desired density and the mature size of the cultivar.
- Planting Depth: This is crucial. Plant the crown (where the roots meet the stems/leaves) at or slightly above the soil level. Planting too deep can lead to rot. The top of the root mass should be level with the surrounding soil.
- How to Plant:
- Dig a hole slightly wider and just as deep as the root mass.
- Gently spread out the roots in the hole.
- Backfill the hole with soil, making sure the crown is at the correct depth.
- Water thoroughly after planting to settle the soil.
- Mulching: Apply a 2–3-inch layer of organic mulch (shredded bark, pine straw, etc.) around the plants, keeping the mulch away from the crown. This helps retain moisture, suppress weeds, and regulate soil temperature.
Planting Container-Grown Liriope:
- When to Plant: Container-grown plants can be planted any time of year, as long as the ground is not frozen.
- Planting Depth: Plant at the same depth the plant was growing in the container.
- How to Plant:
- Dig a hole twice as wide as the container and just as deep.
- Gently remove plant from pot
- Gently loosen any circling roots at the bottom of the root ball.
- Place the plant in the hole.
- Backfill with soil, ensuring the top of the root ball is level with the surrounding soil.
- Water thoroughly.
- Mulch (as described above).
Ongoing Care:
- Watering: Water regularly during the first growing season to help establish a strong root system. Once established, Liriope muscari is quite drought-tolerant, but supplemental watering may be needed during prolonged dry spells. Water deeply and less frequently, rather than shallowly and often.
- Fertilizing: Liriope muscari is not a heavy feeder. A light application of a balanced, slow-release fertilizer in early spring is usually sufficient. Avoid over-fertilizing, which can lead to excessive foliage growth at the expense of flowers.
- Pruning: Cut back the foliage to the ground in late winter or early spring before new growth emerges. This removes any old, damaged, or unsightly foliage and encourages fresh, new growth. You can use hedge trimmers, pruning shears, or even a lawnmower set on a high setting.
- Dividing: Liriope muscari can be divided every 3-5 years to maintain vigor and prevent overcrowding. The best time to divide is in early spring or fall. Dig up the entire clump, and use a sharp knife or spade to divide it into smaller sections, making sure each section has both roots and foliage. Replant the divisions immediately.
- Pests and Diseases: Liriope muscari is generally pest and disease-resistant. Occasionally, slugs or snails may cause minor damage, but this is rarely a serious problem. Root rot can occur in poorly drained soil.
Liriope muscari is a versatile evergreen groundcover requiring minimal upkeep. Plant bare roots in fall or spring, with the crown at soil level. Ensure well-drained soil and sufficient sunlight. Trim back foliage in late winter or early spring.
Liriope muscari, also known as Lilyturf or Big Blue Lilyturf, is a low-maintenance, clump-forming perennial ground cover with attractive, grass-like dark green foliage. It produces spikes of vibrant purple flowers in late summer and early fall, followed by persistent black berries. It thrives in various light and soil conditions, making it a versatile and resilient addition to any garden. It is often used for ground cover, borders, edging, containers, and erosion control.
