Unknown grass, can anybody identify?

Hi,

Here it is (attached). Found in the Netherlands. No idea where to start looking, so started here. If other places or resources are better, please let me know.

thanks you for your time in advance

Panicum virgatum, most likely.
Eragrostis trichoides or spectabilis is another posiibility.

 

Cheers. I'll forward this to the actual gardener, I have no clue :)
