Monkey grass not spreading

Question

After several years, my monkey grass has not spread as hoped for. My neighbor blames the mulch I put around the plants. My wife blames the deer for eating the reproductive parts each spring. I’m wondering if I planted a clumping variety, not knowing they didn’t all spread. Any advice will be welcome. (See Photos)

Answer 1

We did not receive any image of your plants.

You very well may have the clumping form of Monkey Grass vs a creeping variety.
