Annie, PFAF database: Salix caprea pendula
Seed - must be surface sown (not covered and at approx. 70F) as soon as it is ripe in late spring. It has a very short viability, perhaps as little as a few days. Typically grown from grafted cuttings.

If you have seeds now, they are likely several months old.

So essentially the seeds I have will not likely be viable?

It depends on how old they are and how they have been stored. If stored dry and at room temperature, like Morz said, they go bad very quickly.

I think I may be out of luck then. Thanks.
