Liriope

Liriope is a genus of low, grass-like flowering plants from East and Southeast Asia. Some species are often used in landscaping in temperate latitudes. It may be called "lilyturf" in North America, although it is neither a true grass (family Poaceae) nor a lily (genus Lilium). In the APG III classification system, it is placed in the family Asparagaceae, subfamily Convallarioideae (formerly the family Ruscaceae). Like many lilioid monocots, it was once classified with lilies in the family Liliaceae; it has also been placed in the former family Convallariaceae. The genus was named for the nymph Liriope of Greek mythology....read more on Wikipedia.
