Actually Polly, I had asked the question about freezing JI pollen, then on my behalf you asked on the JI yahoo Robin. There was a response, and also a response from J. Copeland published in last fall's Review.
For lily pollen, I have been removing the pollen from the anthers prior to freezing it. I always worry about mold forming at some step though I know that the freezing of the whole anther is commonly done.
I remove the pollen by placing the anther in a 1.5 milliliter microcentrifuge tube, closing the cap, then vibrating it with a back massager. It works pretty well. Then I remove the anther and seal the capsule back up.
I'll try doing this with JI pollen this year. They haven't started blooming yet, everything is just so late here. It doesn't look like I will have a lot of bloom this time around. And some of them I will need to move to a sunnier place, that should help.
