are you refering to the pampas or muhly when you talk about a hardier variety?
Hardy Pampas Grass Erianthus - not muhly.
It was about 4 - 5 + feet diameter and as deep. A male mulberry had grown over it and the grass was not thriveing. So I moved it.
Took most of a day.
And did get cut a bit but that was one time I wore gloves. It took a season or so to catch its breath. I leave it over winter and as I look out the window, it is ~ 7 - 8 feet high on the leaves and the blooms are over 10 feet. Quite spectacular on a bank. As you drive up the street, you can easily see it from a block away.
