Myback Garden -
From what you write, I think also that the "green" pieces are alive. How long has it been in this spot, as you didn't mention, whether you were moving it, or "cleaning up the dead bits" to rejuvinate for the season?
If you need to get it out of where you had it, pot the green parts up in pots and grow on, without chucking them, that way you'll know for certain, and won't feel at a loss, if you chucked them out too early.

PP: It has been in this spot since the summer last year. I planted 3 of them and the others did grow very nice all summer but I did not see any sign of life at all this year...so I dug them up. I was just about to dig up the 3rd when I noticed the green. I am going to leave it where it is and hopefully if this weather we are having changes and it warms up.. it will continue to green and grow. It is looking good so far as I just checked it..I also put in 2 Gracillimus this year ..which I have been told are hardy to my zone..keeping fingers crossed here.. Thanks Deb

Deb -
I'll keep fingers AND toes crossed, but I think you'll be OK. Do let me know though.
I think your new Miscanthus is good down to Z4 or Z5, so I think it's fine too!
Best Good Luck!
