Can anyone identify this grass or weed that has sprouted up in my healthy fescure? Please see picture. I have a pretty good tall fescue lawn that I have been working on getting out the crabgrass and various weeds with "0.28% Barricade pre-emergent Weed-Feed fertilizer applied in late March and a good post-emergent spot-spray weed killer this spring. So far, so good. The fescue yard really looks great. BUT...I have a new patch of this unidentified grass or weed with seeds at the top that just popped up a week or two ago as shown in the picture. It's in an area 20x20 feet only...and it was an area that got a good strong dose of the weed and feed in March. The unidentified interloper is a bit lighter shade of yellow-green (at the top of the picture) than healthy dark green fescue (at the bottom of the picture). And it has what appears to be seeds at the top. I live in zone 7. Thank you. Mark enter image description here

I'm not very good on grasses, but it looks like Poa Annua. A variety of grass contained in a standard mix of grass varieties for use in uk lawns.

  • Rosie, I think you are correct. The pictures I saw on Google for Poa Annua look almost identical. Thanks so much!

  • Yep looks like Pa Annua. People actually intentionally put them in seed mixes? :( It's usually considered a weed. Hard to kill because it's a grass and there may only be one selective herbicide for it. You usually have to kill the whole thing and start over. Spreads pretty fast. Commented May 29, 2016 at 22:52
