The faxonii pollen was dried in a baggie of rice as a dessicant and frozen in early May? or possibly April. Sorry for not keeping accurate records. It's been a couple of weeks at least since I pollinated and had to spray the plant repeatedly for Florida Leaf Footed bugs. Because of the multitude of flowers and bugs I didn't notice my success earlier. It was less than an hour from the freezer to the flower on the pollen.
