It's difficult to be 100% because of the angle of the photograph, but its a weed, and I cannot remember its name for the life of me...

no and i carnt remember it either some call it a mole plant and the seeds spread like mad good luck.just thought could it be caper spurge.

That's it Kenny! Caper spurge, proper name Euphorbia lathyris...

eee by gum i do believe we got it haha

I don't know why I'm unable to remember the name of this, its not like this isn't a question that's asked very often... I've written it down in my notebook now, ready for next time!

it happens to us all bamboo dont worry about it.

Thank you for your help.I love Euphorbias! Just had 5 seedlings delivered this morning from Sarah Raven of E. Oblongata. I will look it up & decide if I want to take the risk of leaving it.

I like Euphorbias too - but the caper spurge is classed as a weed, isn't particularly attractive, and where there's one this year, there'll be lots more all over the place next year. Up to you though...
