Plant details

Also known variously as 'Black Dragon', 'Ebony Knight', or 'Arabicus', this is an extraordinary looking plant with purple-green leaves that turn jet black when grown in full sun and very well-drained soil. As it is so dwarf, it is easily lost in a border and looks best grown on a rock garden or raised bed. Left undisturbed it slowly forms fair-sized colonies and looks good interplanted with small wandering perennials, such as Geranium farreri with its contrasting, lacy foliage and fragile pink flowers. It also makes a good foil for dwarf rock garden bulbs in spring. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).

ophiopogun planiscapus blackbeard offers better coverage and growth, it was shortlisted in the top 20 best new plants at this years Chelsea, we have one growing in a pot on our balcony and it's quite spectacular. Also it had lovely mauve highly scented flowers followed by black berries.


I have grown mine as an edging plant at the front of a sunny border. It offsets the box behind it beautifully. Very easy to divide and grow more plants.
