Slightly spaced out, individual grass looking stalks...what are they

My backyard is an absolute mess that I'm ignoring until Spring. It's primarily dirt, ground ivy and what ever other weeds I didn't spray for that pop up and I weed whack down.

Lately I've had this grass like plant growing, maybe it is grass, but it's growing out in individual stalks sort of slightly spaced out maybe a 1/8th an inch at the most. It's very green and is staying that way despite no watering except a few rains the past two weeks.

It's sort of weird, it popped up about a week ago and it's not growing at ridiculous speeds like a weed...but it's growing spaced out which is unlike anything I can find on the internet.
