Can anyone please ID this grass

[Gardeningtipsneeded]

Hi all, saw this at a local RHS garden today - there wasn’t any ID badge we could see and the nearby staff didn’t know. I’d be very grateful if anyone could help me ID it. Thanks

The stems were very bronze

I think it's stipa gigantea

Or possibly calamagrostis karl foerster!

Email the rhs garden in question, and ask them. Or tell us which garden it is - there are so few that it won’t be “outing” - then someone who knows the garden in question may be able to tell you

Thanks - I really think it’s calamagrostis as above!! Thanks so much
