As I receive or harvest seed I store it in my freezer until I sow or distribute it. A good deal of my experience has been with rhododendron seed that I find retains viability for a very long time: perhaps 5 or 6 years ... I find freezer storage is "dry" and I use no dessicator. Are there any comments on shelf life of "alpine" seed in general?? E.g., what expectations should I have re: say, Townsendia ... or Eriogonum ... or is this just too general an issue (putting aside the issue of "ephemeral" seed). Some comments?
