ID please!

I feel like I should know this one. I've seen it everywhere, pretty much my whole life, but I am drawing a blank!



It's the small-leaved plant in the middle, between the hydrangea at the back and the iris at the front. With the red berries, if you can see them.

I found it when I first moved in as a teeny tiny two-branched scrap, popped it and the hydrangea in the (then) bare soil behind the pond and promptly forgot about them. The other week I cleared the rampant brambles out of there and it reappeared!

As an aside I am dead chuffed to see how well the jasmine is doing this year, it's struggled with those infernal brambles from the get-go but it's really got going now

 

I can't see it very clearly but could it be cotoneaster?

 

Will second @Lorea, definitely looks like a Cotoneaster but probably the Verticalis type as it looks to be spreading quite high. The normal Cotoneasters tend to stay low and are good ground cover plant.

Whichever type they spread very easily because of all the berries and are quite easy to remove until the get really woody stems.

 

Thanks guys. I would guess that it's high because it's been buried in other plant life - it's just going upwards to the light.
