What plant is this?

Hello gardeners! 

Does anyone know what this is? The spikes are hard and very spiky/sharp at the ends. 

How big might it grow? 

I’ve recently moved into a new house and this am trying to figure out what the previous owners planted :-) 

Many thanks!

    It could be Festuca Glauca. They don't normally grow that tall. Probably no more than 40cm tall.

    It's not festuca. It could be Juncus Effusus.

    I consider it to be an invasive weed, don't let it seed whatever you do.

    I don't remember my festuca having those tubular looking leaves which look a lot the wild rush that spread all over the Belgian garden if we let it.  Looked a lot like Ceres' juncus effusus and it spreads by its roots as well as seeds so beware.
