What species of weedy grass is this?

11 years ago

I have a BUNCH of this grass in my backyard. (see photos below) It is not crabgrass or silver crabgrass. I thought it may be barnyard grass, but the seed heads are totaly different than those of barnyard grass. I think it may be some sort of rye grass, but I don't know for sure. Does anyone else know what species of grass this is?

P.S. Photos from Photobucket look a lot better in posts than those from Flickr.

Here are the roots and underside of the plant:

And here is one of the seed heads:

That could be either Annual Ryegrass or Annual Bluegrass.

Thanks, kimmsr. Now that I was able to narrow my search I googled "Annual Bluegrass" and that is exactly what it is. Now I need to figure out if it is a desirable grass or just more weeds and how to get rid of it if it is a weed. (I wonder if Haltz will prevent it from sprouting again next year?)

These annuals are considered by many to be "weeds" and they usually die out shortly so nothing, other than removal, is needed to be done.

Well, I'm trying to establish Bermuda grass in my back yard, but the annual bluegrass has taken over so they have to go. I sprayed round up last night. after they have died I will rake them up and then plant the Bermuda sprigs.
