What is the common name for Liriope muscari?

The common name for Liriope muscari is indeed Blue Lily Turf. This perennial plant is well-known for its grass-like foliage and spikes of purple flowers that appear in late summer and early fall. It is often used as a ground cover or edging plant in gardens and landscapes, particularly in shaded or partially shaded areas. The term "lily turf" reflects its grass-like appearance, while "blue" refers to the color of its flower spikes.

The other options represent different plants entirely. Fountain Grass is known for its feathery flowers and airy appearance, while New Zealand Flax features broader leaves and is more tropical in appearance. Black Mondo Grass, while also a grass-like plant, belongs to a different genus and has darker foliage than Liriope muscari. This highlights the uniqueness of Blue Lily Turf among ornamental grasses commonly used in horticulture.
