Plant ID help please

Can anyone identify this plant please? It grows in a thick clump under some large trees, has ribbed 'rough' leaves, and a 'flower' on a long stem.

It's a bamboo. Possibly one of the Sasa group - but don't ask me which - I don't care for any of them.

I like that, neither do I, horrible plants which I spray whenever I find one.

Thank you. I did wonder if it wasn’t a keeper.

Well, that was definitive - wasn't it!

It looks like palm grass -Setaria palmifolia - and it IS a pest plant. Don't let it set seeds - every one grows. My neighbours thought it was attractive. Not too hard to dig out though. I'm still digging out seedlings.
