In the garden
Liriope muscari 'Big Blue' is a clump-forming perennial from East Asia, valued for its narrow, strap-like leaves and lilac-purple flower spikes that appear from August to October. Plants reach about 0.3 m and are used where a low, grass-like texture is required in the border. Place Liriope in full sun on sandy or loamy soils with good drainage; the cultivar will tolerate soils that remain moist provided water does not sit around the roots. It carries a UK hardiness rating of H7, meaning it is fully hardy across British gardens; its USDA range of 5–10 indicates similar cold tolerance for those comparing climates. Keep soil reasonably free-draining and avoid waterlogged planting sites. Liriope muscari 'Big Blue' works well as a ground cover between shrubs, a neat edging for paths or borders, or to fill narrow strips where a low perennial is needed. Plant in groups for best effect so the lilac-purple spikes are noticeable from August through October, and expect tidy 0.3 m clumps that provide structure around seasonal planting.
