Can I bring my fountain grass indoors or cover it in the late fall? I thought it was a perennial for my region. (Pennistum x advena 'rubrum')

Dig them up and overwinter these plants by placing them in pots and moving them to a cool (not cold) but dry and dark location. Many people use garages, basements or even closets. Let them die back. Water the pots once a month and bring out when you either see new growth or the temps outside average about 50 F. They will grow back after that.
