Evergreen shrub ID

I saw this in Chester in a park, I've always walked past it, and thought it looked too delicate to be an evergreen shrub.. but it is, the leaves are surprisingly sharp, and rigid.

Anyone got any idea?

ps its not Callistemon (bottlebrush)

 

Ruscus aculeatus or wild myrth .....grow wild all over the mountain of Italy and produce red berry in September .......yes it`s really hardy

 

Thank you Sal.. well it has to be hardy growing in Chester! I think it's mildly attractive, although the reason I ID'd it mainly is due to the fact it stands out from the other plants for some reason.. it was actually in flower today. Tiny flowers though

 

I`m originally from south Italy , it`s a zone 10, we have summer that can reach a record 45 and winter that can go to - 4 , but the mountains are really high and can touch temperature of -12 .....think about how many mediterranian plants can be grown in UK .
the wild mirth is used for xmas decoration and yes has a small dark flower , I do remember that plant as when I was kid , I was going on the mountain to collect wild oregano , rosmarine, laudano, arbustus fruit , chestnuts , pine , sorbes , wild strawberry and in easter time wild asparagus .......now that I`m thinking about all of this plants are growing over here as well .

 

It is known as Butcher's Broom in Britain and is native, but usually only found in the warmer drier South, so the Chester ones are probably planted rather than indigenous. We did have them in the woods near my mother's in Somerset.
