Hallo Bertil!Ser du holder til nær Vänerns brädd! Then you have a rather mild climate, I presume?
Rogaland, Norway - with cool, often rainy summers (29C max) and mild, often rainy winters (180 cm/year)!
I think it is a Hepatica nobilis alba but it is difficult to see that in the small picture. Hepaticas grows in abundance around here and is a big favorite,
