I don't know what others feel, but I find it difficult to ID some plants (especially the grassy ones) unless I can see them in situ. That way, we can see their growth habits, color contrast, texture, etc.

Not a grass. Possibly a weed. Have you seen flowers?

No flowers. I will take a photo of one of the patches so you can see it "in situ." Is it possible to post the new pic to this thread or do I have to start a new one? I don't see and option for adding a pic once a thread is started. Thanks if anybody knows how.

I'm quite sure this is it (prostrate knotweed). Click the link below.

How about this? This is a good possibility.

Some plants called Jewgrass or Jewel weed will have blue flowers
