Liriope spicata
Creeping Lilyturf
This grass-like semievergreen perennial is native to China and Taiwan.
It produces a stalk of lavender flowers in late summer, followed by black berries that persist into winter.
Grows about 1 foot tall and spreads aggressively through rhizomes even in deep shade.
Its rapid spreading growth habit has caused Creeping Lilyturf to be classified as invasive in some states.
Drought tolerant and deer resistant.
