Does anyone have any idea what these plants might be?
I have lots self seeded on the patch where I planted my onions in the autumn, and others elsewhere.
I presume it must be a flower of some sort, but I can't work out what 

Thanks

Not sure, maybe Cat's ear, but I'd dig it out whatever it is

Yes I agree with Mum,  -  get rid.  Mrs Bouquet

Possibly cornflowers seedlings given that bloom across the leaves though

Oh dear!
I can see the similarity to cat's ear, but I have definitely had cornflowers on the plot in the past.

So, I have removed them all from the onion patch, but saved a few in a safer place to see how they turn out!
Hopefully they will be cornflowers.
Or its in the bin with them 

Thanks for your replies
