What type of grass is this?

Notes:

Several years ago, I noticed some patches of grass that were a lighter shade of green than the fescue (and weeds) that it was growing in. The blades are thinner than fescue, and the texture of the grass is more open than fescue. I’ve included a picture comparing the grass to the surrounding grass which is mostly tall fescue, as well as a close-up. Any ideas?

Thanks!

    Looks like it may be creeping bentgrass: Agrostis palustris. It often looks greyish green compared to surrounding fescue. msuturfweeds.net/images/galleries/c_bent/1.jpg

    One other thing I should have added… this stuff is slowly spreading.

    Bruce I should have asked if the patch stays green during the cool season. Of course if it doesn’t it isn’t a bent grass variety. As you mentioned it is slowly spreading and that is typical of bents as weed in Metro Atlanta cool season lawns. I mentioned the greyish green color of creeping bentgrass and that is incorrect. Another bentgrass variety is common colonial bent and that has more of the characteristic greyish green color. Colonial is what I occasionally see as a grassy weed in fescue during the cool season. Check this link on Colonial bent: http://en.wikipedia.org/wiki/File:Gewoon_struisgras_Agrostis_tenuis.jpg The bents are not real happy in our Georgia climate even with extremely high maintenance.

    Thanks for your reply, your guess of bent grass seems to make sense. So, is this the stuff that if you cut it really, really short, it’s supposed to look nice, like a putting green? You’re right about this stuff not liking our climate very much, during the summer, it’s king of yellow looking, but stays green in the cool season. I guess to kill it, I’d have to use something like roundup, kill it and everything around it, and then reseed.

    I believe it to be Orchard Grass, a “pasture grass”. I just emailed Walter about this hoping he had an answer for controlling it. It is highly invasive and as far as I can tell only Roundup will kill it along with your fescue. Pre emergents didn’t work. Only attacking it early and regularly will prevent if from taking over your lawn. It seems to have come in Kentucky grass seed which does list some pasture grasses at about 5% but not this particular one. Having an entire lawn of this grass doesn’t work because it looks awful in the hot weather. Lawn services might be spreading it with shared mowers. I think it will become an epidemic in Atlanta.
