Q: I want to plant Gyoku-ryu mondo grass in a large shady space beneath trees. Any suggestions? 

A: Common mondo grass, Ophiopogon japonicus, spreads easily from individual plants. But the variety you have chosen is extremely dwarf and spreads very slowly. I have a clump of it I planted five years ago that has expanded only an inch or two. Look for dwarf mondo grass, Ophiopogon japonicus ‘Nana’. It grows a few inches taller than ‘Gyoku-ryu’ but spreads faster
