Help! Mystery plant, not Nigella :(

Hi there,

I sowed a packet of Nigella 'Moody Blues' last month, but the plant that has grown is a complete mystery! The flowers & foliage are nothing like what's shown on the seed packet.

Can anyone tell me what I've got here?

Thanks for any help.
Jenny

 

I have a weed in my garden that looks like that, aint got a clue what it is though.

 

Hey Pete
I've just found out that it's Common Fumitory.
