Hi  could anyone identify this plant please. They look like purple berries. A friend saw it and we can't place it. Any help appreciated thanks

Liriodendron

Could it be Liriope muscari 'Royal Purple'?

Def. Dianella.

Liriodendron

I've learnt a new plant...

It is not that common.
Native to New Zealand.
I love the fab berries.

Liriodendron ...Liriope muscari have spikes of  upright flowers followed by berries.

Yes... there's a Liriope with purple berries, but you're right, the stems are much more stiff and upright.  
I guess Dianella is a bit more tender...
