Ohiopogon 'Nana' (Dwarf Mondo Grass)
Dwarf mondo grass is a tough little plant that pops up in many garden designs. It’s ideal for using between pavers instead of pebbles. The most commonly grown dwarf mondo in New Zealand is Ophiopogon 'Nana', which matures at around 100mm high.
When you plant mondo it’s best to plant lots of small plants planted closely together, rather than a few bigger plants scattered about. Some professionals plant them around 10cm apart, using a staggering 200 plants per m2 😱.
But don’t call the bank just yet 💰, these are small ‘plugs’ or divisions, not full-size plants 😅. You purchase the mondo in ‘trays’ that yield around 50 divisions per tray.
The reason you should plant lots of little mondo grass plugs so closely together is so that weeds don't have a chance to establish between the plants between they 'join up' in the same way as when you use just a few larger plants, spaced further apart.
