Ophiopogon planiscapus ‘Nigrescens’Cottage Garden

Common name Black grass, native to Japan. The flowers are white to pale lilac with strap leaves that turn from green to black. The berry’s produced in winter are a shiny black . This plant is commonly used in rock gardens or raised beds as an ornamental plant as due to its dwarf qualities it can be lost in borders. The seed can sometimes revert back to green which should be removed where you wish to form a black mass. Under planting with bulbs can also give dramatic impact against the black foliage. Grow in full sun and well drained soil. At Sissinghurst we use it as ground cover under a rose and clematis screen.
