Ophiopogon planiscapus var. nigrescens ‘Edge of Knight’

White Edged Black Mondo Grass A rare form of this evergreen lily relative, with ¼ wide leaves and short stems of blue flowers in summer, producing tight clusters of shiny black pea size berries that hang on all winter. Sun or light shade. This Japan selection has a thin white edge on each black leaf. Subtle, but very cool. A collector's item. z5
