Looks like

switch but very dark. This was taken last week in an area that I had cut this spring and then hit with 1/2 strength round-up. Also some bunch grasses in the area.

I've got patches of some grass that looks alot like this. They are seeding right now. The whole patch looks maroon because of all the seed heads. Any ideas?

Happy Birthday Larry!

OB- happy birthday. Did yours just show up or when did you notice? Soil disturbance, seeding, or spray?

It's not switchgrass that's for sure...I think it's tall fescue but I'm not an expert on identifying fescue either.

Tall Fescue

If it's fescue then it will require several does of roundup and followup burns to kill it. Seed will still sprout after initial kills...pain in the butt to get rid of and it's worse then worthless for wildlife.

Whatever it is...you don't want it!

I really don't think that it is tall fescue, it may be Purple lovegrass. Tall fescue has seed heads that are wrapped tightly around the stem, where the purple love grass branches out and the seed turns "purple" when matured.

Don't know for sure, but looking at the weed guide, that would be my guess.

Found this great ISU site.
Could it be Red Top? grass of Iowa

I could go with red top or maybe purpletop. USDA. I also noticed that it is not on their noxious weed list.
