Ophiopogon japonicus, common mondo grass, forms tufts or clumps of dark green, needle-like foliage. It grows to a maxium height of 30cm and makes an excellent border dividing garden and pathways. It is often used to cover large shadey areas as it spreads reasonably quickly and looks great as a border edge as shown above. Plant 10 to 15 cm apart for a hedged border.  The price is per plant.
