Does anyone know the name of this grass?

If those seedheads still contain seeds I'd try sowing some, anyway. After all, when you buy seed it isn't usually in its unripened state.

Sorry, can't help further, I've no idea what variety it is.

It's very difficult to tell from that photo, but maybe a Molinia. It's very upright.

Is it Feather Reed Grass?

Thanks, I’ll search that, or, as MaizieD says, just collect the seeds ( and hope for success)

I searched all the Molinia. It’s a caerulea I think 🤔

Scrubb the above. Callistemon21 has it, yeh 😄well done you 👏👏👏

I agree that it's feather reed grass. Look up Calamagrostis x acutiflora. The seeds of popular species such as "Karl Foerster" and "Overdam" are sterile.

It looks like Calamagrostis acutiflora Karl Foerster.

Snap Caravansera 😃

It looks like Calamagrostis acutiflora Karl Foerster.

There's posh for you 😁

Now I’m really getting confused 🙃 and it doesn’t take much.
Here’s a pick of the seed head.

Calamagrostis x acutiflora 'Karl Foerster' is a Feather Reed Grass!

I’ve got that in my garden and it doesn’t look like the photo? 🤔
