Liriope muscari Big Blue 2ltr

Liriope muscari ‘Big Blue’ (often called lilyturf) is one of those “where-have-you-been-all-my-life?” plants for tricky spots. It forms a tidy, evergreen clump of arching, grass-like leaves, then in late summer and autumn sends up upright purple flower spikes (like little grape-hyacinth towers) that add colour just when many borders start to slow down. It’s brilliant as edging, underplanting around shrubs, weaving through shaded borders, or filling awkward gaps—smart, resilient, and very low-fuss once settled.

‘Big Blue’ typically grows to around 30cm tall with a spread up to about 45cm, making it ideal for neat ground cover without overwhelming neighbours. 

Planting Instructions

When to Plant:

Plant in spring or autumn, while the soil is moist and workable. Container-grown plants can be planted most of the year, avoiding periods when the ground is frozen or waterlogged.

Where to Plant:
Choose a position in partial shade or shade for best results, although it will also grow in sun if the soil does not dry out. Liriope prefers moisture-retentive, well-drained soil and is ideal for shady borders, woodland-style planting, under shrubs, ground cover, and edging paths.

How to Plant:

• Depth: Plant so the top of the rootball is level with the soil surface.
• Spacing: Space 30–45 cm (12–18 inches) apart, depending on how quickly you want it to fill out.
• Soil Prep: Mix in garden compost or leaf mould to improve moisture-holding, especially in lighter soils.

Watering:
Water well after planting. Keep the soil evenly moist for the first growing season. Once established, it is fairly tolerant, but will look its best with occasional watering during prolonged dry spells.

Aftercare Tips:

• Tidy up in spring by combing out or cutting away any tired foliage before new growth starts.
• Apply a light mulch in spring to help conserve moisture and feed the plant.
• Divide clumps every 3–4 years in spring if you’d like to rejuvenate plants or increase your stock.

Top Tip:
Liriope ‘Big Blue’ is a brilliant partner for Hostas, ferns, Heucheras and Japanese anemones. Plant in drifts for a really smart, modern look and to create easy, weed-suppressing ground cover.
