I have a 500 foot long berm I need to cover that averages 4 ft high. I can
get to the top with my riding mower but the sides are too steep and require
a push mower or trimmer. Any suggestions on low growing ornamental grasses
or plants that will not take over, are attractive, and won't cost me a
fortune that I can plant on the sides?

Zone 8, North Texas. 100 degrees today.

Ground covers such as Pachysandra, Myrtle or Sweet Woodruff. It will
take a few years to get full coverage.
