Grass feed - can you identify it?

[rgon]

Hello! The time has come for me to ask a question here after many weeks of reading. I have a LARGE abundance of this type of grass by my house that I could cut and feed my rabbits in addition to pellets. Can someone please tell me what type of grass this is and if it is safe to feed? Thanks!

If that's Johnson grass, then not safe. Pull a clump, get pics of the stem, roots, where the leaf meets the stem and seed/flowers if they have them.

Looks like roseau cane to me. If it is, be careful. The leaves and stalk will cut your hands if you try to pull it. Not sure if it is safe for rabbits.
