Can you identify this plant?

This plant decided to live in my garden about 10 years ago. It is about 12" tall and wide. Even if it's a weed, it's a very pretty, well behaved and welcome one! Sorry it's not a very clear photo.

Thanks Bren and Bamboo, that was quick. I'm off to look in the book

Yes I think you're right Bamboo, it does look like Corydalis lutea. Thank you both for your prompt answers.

i have this and it self sows all over but it is lovely.

Mine is unfortunately very restrained in self sowing but I have just found 5 'babies' growing underneath which I am delighted about. Very pretty.

I love this, too - I've got it 'going' at last! I hope it seeds itself!

Being as this is evergreen, can it be treated like a hardy geranium. i.e. given an all over haircut to promote a new mound of growth?
