Add to wishlist Remove from wishlist
Black Mondo Grass. One of the classiest ornamentals and maybe the best for providing color and textural contrast, this can find a home in any garden. Fairly drought tolerant but thriving in more moist situations, this has evergreen (or everblack) leaves with pink flowers and shiny black pearl seeds. The cultivar names 'Nigrescens', 'Niger', and 'Black Dragon' have been very recently subsumed into 'Kokuryu'.
