All these are a foot or taller. With everyones guesses and a little more research, I found a few things.
Still at lunch on #1. I didn't check the grass it's self, the plant has anywhere from 4 to 7 of these seedheads and that is all. No leaves on the stem or skyward, all leaves are close to ground and the seed stalks are over a foot tall. Only a few of these I can find, no where near as common as everything else pictured. To me that means pull it.
Neat site here
I dont know if 2 is bluegrass or not. Looks like it but most bg seedheads, in a lawn anyways, are only 2 or 3 inches tall. The #2 in the pic is a foot or better in the field. Maybe a big bg or just really healthy?
4 is tall fescue.
I think 3 & 5 are both orchard. Immature and mature
Thanks for the pointers an motivation everyone.
