Some pollens will keep for years if dried and then stored frozen. There are claims that Clivia pollen can be kept viable for more than 5 years. Hemerocallis pollen keeps for at least 3 years. Crinum pollen keeps for at least two years. Hippeastrum and Hymenocallis pollens usually last only a bare one year in storage. For long-term storage, both drying and freezing are important.
