I would guess a variety of Deschampsia cespitosa. You can move/divide in spring right after you see new growth starting up.

Thank-you pudge - I googled some pics and it looks like you're right. I'm not experienced with grasses and was wondering if it would survive a move at this time of year? We are in reno mode and it would be more convenient. I could live with a growth set back but if it meant probable death I would wait.

Thanks - Susan

It's a cool season grass, Susan, best moved when it's putting on growth in spring so they say. I suspect it's either already in or approaching dormancy and it won't get busy putting out roots if moved now. I've never moved an OG in fall so I can't say one way or the other if it'll survive, but if you really don't want to lose it, then I'd wait. On the other hand, if you can get the entire root ball with lots of soil so that it doesn't disturb the root system at all, then perhaps it'll be okay to move, but maybe wait until spring to divide it.

Thanks for the great info pudge. I think I will do as you suggested and move it as one large clump and consider dividing in the spring. I am moving it to a more open space where it might not look as large as it does in the cramped space it currently occupies and I may not want to divide it after all.

Thanks - Susan
