Three large walnuts were just given to me.  They come from a tree just up the street.  My friend's dog had broken into one of the nuts so we opened it completely to reveal a most beautiful sight...  Taste is excellent!  The other two have been planted.   I photographed the remaining half nut meat and thought I'd share it will you all too.

I have never before seen one. 

An Internet search makes references to a California Plantation.  No mention in Wiki.  They must come from somewhere.....   Remember... I'm in Austria.   Would bread from this walnut be purple... or some other color?

A feast for the eyes!
