Grated the still-hard coat...no go.
Pounded it with a hammer until crack appeared.


"white dot" = radicle?


No apparent rot, the husk cavity was almost entirely filled by the embryo?
Does the radicle break through from the inside?
Or does the husk have to rot before the radicle can emerge?
Or both in unison? Resembles a walnut.
I'm guessing the other Bizzie seeds will take another 3-4 months to pop.
