Since it sprouted from the driftwood, it could be a marsh-type grass. You probably won't have any trouble keeping it happy right where it is. It may even produce an inflorescence for you after it matures.

Please keep us updated!

Whatever it is, it's a very nice looking plant that compliments your tank well. Keep it growing!

I have no idea how to propogate the thing, and I don't want to get rid of it....so, I'm stuck.

Awesome. Just FYI, if you want to propagate it and stick some in the other driftwood cracks, you can split the crown (it looks to me like this type of grass would be a great candidate for splitting) . Let it get some more growth , then gently pull or carefully cut the crown into a couple or more plants (each with roots and shoots) . Just looking at your pics, I see 4 viable plants there.
