Ophiopogon planiscapus Nigrescens or Black Grass is a very striking plant. Introduced originally from Japan it is the same family as Asparagus (Don't eat it!). For the very best black leaves it needs to be in full sun and very well drained but moist slightly acid to neutral soil. Will still grow well in lesser locations (no lime) but will be more of a purple black. In summer small spikes of delicate bell shaped, pale mauve flowers appear, followed by spherical, dark blue fruit. Ophiopogon planiscapus Nigrescens forms clumps so will spread over a wide area given time. Lift and divide if it becomes too much. Plant front of border and ensure it is not surrounded by faster, larger growing plants that will swamp it. A very popular plant much loved by designers. Can easily be grown in a pot or container. When growing in a pot or other container use a good quality ericaceous compost for best colour and ensure you feed regularly as a hungry plant is a poor performer. We recommend Osmoscote pro 5-6 month applied in the early spring. One application gives all the nutrients the plant requires for the whole year.
