I have no idea but it is very pretty!

Hi guys
I wonder if anyone can help with this, it is a bush which over the last several years has grown to about 3 foot high, the flowers do have a faint scent but not anything startling. It sends out suckers (which is great if I knew what it is! lol) but I just don't know what it is, I have searched and searched and looked at thousands of bushes with dark pink flower, still no clue!

 

Possibly Rubus arcticus.

 

It could well be, the leaves are very similar and we have planted it beside fruit bushes but I don't remember it having flowers or fruit before. Also the petals on mine are in multiple layers and so far the ones I have found online are single petal layers. Thank you though, I will do some more searching.
