I have about 80% success germinating Aronia Melanocarpa (Black Chokeberry)
from seeds I harvested from fruit last fall.
They needed 110 days in the fridge in damp paper towels under plastic wrap on
a plate. I have about 36 seedlings.
Washing this fruit is a bugger. It has the worst slimy coating I've ever
encountered, but apparently that didn't affect germination enough to fix that
problem. After 110 days, I could actually see small sprouts on some seeds!
That means, Plant Now!
