Each catkin contains many nutlets which appear to be discs with a bump in
the middle. If the catkin hasn't dried out completely, it has not
entered its deep dormancy so it can be sowed and covered with a thin
layer of sand or fine peat moss to maintain moisture. Germination
percentage may be very low, hence the need for prolific seed production
on birch trees. You do realize that you could get really crappy
seedlings since birch outcross almost exclusively. I imagine that the
same seed situation applies to willow, but why don't you just take
hardwood cuttings in the middle of winter after vernalization is
satisfied and root these, then you'll know what you're getting at least.
