Hardy grasses for pots?

[NanooCov]

Any recommendations for a nice hardy grass that will do well potted in a sunny position? Something with nice coloured foliage (maybe a russet/red colour?) would be nice but anything considered.
Thank you!

I have a lovely bronze Carex, in a pot. It grows like an unruly mop of hair. Sorry I don’t know it’s variety name, I’ve had it a long time. The seed heads are very small, but little tufts of self seeds plants pop up ready to plant elsewhere or give away.
I grow another Carex that has dark and lime green leaves in the same pot. It’s a bit more compact.

Thanks - will take a look at Carex
