Corydalis Lutea

This comes up in the garden every year for a few years, it has not come back this year :(((

It loves my soil Michaella, and pops up here and there, generally somewhere shady and cooler. I never deliberately planted this flower. thank you for your other comments.

I have given rooted bits of Cory to several friends and neighbours but she is loyal to my garden. She is very picky.Seriously do not know where she came from, probably as a side serving in a bought plant.
