Stephen McCabe of the UC Santa Cruz Arboretum gave a presentation to our club last year on Dudleya. I asked him how they store seed and for how long it remains viable, given that Dudleya seed is very fine. He said they store it at room temperature and that it remains viable for 7-8 years.

They sense the daylength around them, and so may prepare to germinate at the appropriate time. What does a thermostatically controlled fridge do to them? I store all my seeds (in Los Angeles) at room temperature until the appropriate season arrives - including those from overseas - with good results. Refrigeration is a crutch for those with limited time or space, and shouldn't concern those people who can sow their seeds within 12 months of receipt, assuming fresh supply (that is anther question). Seeds that I might store for 10 years? - well, they should either be thrown out into the yard or given away, since they are clearly of no importance!
