Ophiopogon planiscapus

A dense evergreen, low-growing, slowly spreading broad leaved grass-like plant, with dark green foliage. The small lilac flowers in small clusters in summer are followed by large blue berries which are attractive when found hidden under the foliage. It is slowly spreading via short rhizomes so acts more like a clumping plant. Prefers shade. Lovely planted as an edging or in a pot.
