It might help if you take the picture before you mow so we can see the tips of the grass. Does it ever get flowers or seed heads?

Also does it turn brown in the winter?

I've included a couple of new pictures showing some individual blades that weren't mowed but yes, I wish I would've gotten pictures before mowing. I could wait a couple of weeks if that would help. My 3rd picture includes a grass that seeds but it might be a different grass type than the turf grass. There was quite a bit of that seeding grass before I mowed and it was tall. I'm sure I'll be seeing it for years to come. I don't remember seeds or flowers from the turf grass but there are quite a few weeds and different grass types growing throughout.

Thank you

On my run this morning, I remembered that I didn't fully answer you. The grass was browner in the winter but it wasn't being watered with the sprinkler system at all. The grass greened up with our SoCal late winter/early spring rain, although much of the green was also the abundance of weeds coming through.

I was able to find another picture of the grass this morning (not the best picture as a lot of sun, unfortunately) from February before I mowed.

Well the new pics help to eliminate my ideas for what the grass is. Sorry.
