Ophiopogon planiscapus 
A member of the lily family, black mondo grass is the most unusually colored plant that we grow. Its narrow grasslike leaves are so intensely purple-pigmented that they look black. In addition, it bears numerous dainty pink and whitish bell-shaped flowers upon upright stems in summer, followed by bunches of shiny black pearl-shaped fruit in fall. Transform your yard with the exceptional beauty of black mondo grass today.
