Also known variously as ‘Black Dragon’, ‘Ebony Knight’, or ‘Arabicus’, Ophiopogon planiscapus ‘Nigrescens’ is an extraordinary looking plant, with purple-green leaves that turn jet black when grown in full sun and well-drained soil. Its dwarf habit means it’s easily lost in a border, and so it’s therefore best grown on a rock garden, container or raised bed. Left undisturbed it slowly forms fair-sized clumps and looks good interplanted with small perennials such as Geranium farreri. It also makes a good foil for dwarf rock garden bulbs in spring.
For best results, and the darkest foliage, grow Ophiopogon planiscapus ‘Nigrescens’ in very well-drained soil in full sun. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
