Weed invader?????

Hi all

I keep finding this plant popping up all over the place, i pull it out when i see it but saved a bunch out of curiosity to see what it does

Any ideas????

 

Spurge?




If so, spurge sap can cause a skin rash.

 

Bluuurrrgggg.....not sure i like the sound of that.....just googled it and it doesn't really get colourful flowers so i think it has to go

Thank you
