Are these seed heads annual bluegrass?
I have a lot of seed heads in my lawn right now and am trying to determine if this is "annual bluegrass" (Poa annua) or something else. The seed heads are only about 5 to
6" high and appear to have a purple tone to them. Can you please identify this and tell me if it's friend or foe?

Unfortunately, your photo is too blurry for me to identify the grass. Even if it was clear, I might not be able to.
Bluegrass goes to seed about this time of year, so you could be looking at normal Kentucky bluegrass seed heads. Poa grass has a characteristically lighter color than normal bluegrass. This usually makes it easily identified in the lawn.
