... But I wonder
why seeds need to be dry instead of green? Has anyone given a science
explanation or is this merely someone's wishy washy attitude.

I don't know the answer for this species, but delayed germination can
have a survival benefit for some species.

Delays can get the seeds past difficult seasons or conditions and
start the seedling growing at a more propitious time.

Delays can also give seeds more chance to disperse, allowing the
species to colonize a larger territory.

Perhaps the drying out functions as a delay timer, or perhaps it
signals to the seed that it is in sunlight, away from the shade of
the parent tree or other plants.

All just speculation on my part.

Good luck with your seedlings.
