B3, sorry meant to say. rubrum is tender. needs over wintering indoors and, from memory, needs a minimum of 4 degrees over winter. It is a difficult grass to overwinter too because it needs some moisture, light and to keep growing.
A hardy alternative red grass ...but deciduous...is Imperata Red Baron. Ofhers,,evergreen, are uncinia unciniata rubra and carex buchannii and comans bronze.
a medium well behaved "lighter" grass check out panicum shenandoah...it is now developing delicate flower heads and crimson foliage
