Ident my plant!

[CuttedUpPear]

I know you lot love a bit of plant identification. As do I.
But I can't remember for the life of me what this plant is called - it's 5' - 6' high at the moment, and the berries remind me of capers....

I've been thinking spurge but then again. ..something with tri in the name?

I've got one of these but no idea what it's called. Selfish bump!

It's euphorbia lytharis or caper spurge.

Thanks echt
I've a feeling I should pull them up before they seed everywhere - they look the type.
Although there is a nursery selling them at £2.60 per plant
