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. CJ Addington
