Love in a Mist (nigella)

Lots of self seeded flowers at the allotment which were attracting lots of bees...which I failed to photograph successfully. These have appeared near our blackberries and there are others in between rows of potatoes!
I always used to call them Love in the Mist ( I think that’s what my mother called them) but have just looked up the name and it seems it’s Love in a Mist
