Need help, again!

A friend, who actually is a very knowledgeable gardener, has this plant in her garden. She has no idea what it is, I think it's been there for some time. From what she says, there are no flowers to speak of. I more or less promised her, that one of you clever people would have an answer!

 

It is a Polygonatum sp.
I believe it may be one of my favourites..... Polygonatum verticillatum.

The tiny flower buds are just showing on your pic.
Followed by red berries.
It then turns a beautiful golden colour in the autumn before dying back ..to reappear next spring.

 

Thanks for your answer, so sorry I have taken so long to get back to you! It certainly looks like you are right.
