Hi Brian!
    I have successfully pollinated Dracunculus using frozen pollen, so I
know it can survive the freezing. I just put pollen-coated carrion beetles
in a clean glass jar and covered it with foil. When I later dump the frozen
beetles into freshly opened blooms, they set seed quite well. I have only
stored the pollen for a couple of weeks, waiting for a good bloom to open,
so I am not sure how long the pollen would last. I would think that if you
kept it dry and didn't subject it to fluctuating temperatures, it should
last quite a long time.
