Liriope Big Blue
This lilyturf cultivar is a tufted, grass-like perennial which typically grows 12-18" high (sometimes to 2') and features a clump of strap-like, arching, glossy, dark green leaves (1" wide). Clumps slowly expand by short stolons, but do not spread aggressively like Liriope spicata. Erect, showy flower spikes with tiered whorls of dense, lavender flowers, somewhat resembling grape hyacinth (Muscari), rise just above the leaves in late summer. Flowers give way in fall to blackish berries which often persist into winter. Evergreen in the South, but foliage can turn brown considerably in areas with cold winters such as St. Louis.
