Can anyone identify this plant for me?

I seem to have 3 of them in my new garden...

Euphorbia, this has sap that is toxic.

Oh nice, I like euphorbia, I have one elsewhere but leaves are a bit different. I'll be careful when cutting it back, thanks!

I agree. They spread everywhere, I'm always digging some up.
