Is this a grass or a weed? #449895

Asked April 26, 2018, 5:55 PM EDT

I have what could be a grass growing in my side yard. It is a lighter green than the fescue. It has circular stalks and it is not flexible. It is stiff. I wouldn't walk barefoot through it. I am attaching pictures. Some of it grows sideways.

Frederick County Maryland

Your first photo looks like poa trivialis (roughstalk bluegrass) a weed grass.  
It also shows some poa annua (annual bluegrass) in the lower left-hand corner.
