Hi, thanks for all the replies and sorry for the lateness of my response.
It's definitely not Californian poppy. This is a favourite of mine and I have several in the garden. The CP has lighter green leaves, which are more delicate than the plant pictured. The stems of these are more fibrous and stronger.
Smell I can't tell you at the moment. Because of age and years of smoking my sense of small was poor, and then a reaction to medication for allergic Rhinitis killed it off completely a few years ago. It's recently started to return but some days are better than others.
I don't think it's one of the corianders because I also have these in the garden and they grow much taller or have different leaf forms.
Nutcutlet, you might be right about it being an umbillfer (now Apiaceae), but as yet the ones I've had either haven't matured to the flower stage, or I've pulled them out too soon, but they don't ever seem to have much height, staying quite close to the ground.
Definitely not Nigella as again, I grow these and the plant pictured is much bigger and doesn't produce flowers. The leaves and stems are also different.
I'll let one, or maybe two develop, and then come back to this thread with more info and better pic's.
