Hi sbb!

I discovered purple walnuts:

I'm impressed. Are they well known, or shall I trace their source
(maybe from one of our trees) and give some to ppl to cultivate
them? Can they grow when already opened? How would you best
germinate them?

Are there any external indication to their purple insides, eg skin colour?
