My experience with seed from western South America has been that the best 
germination is achieved by storing the seed dry at room temperature over 
the summer. I just leave it in paper packets in a box in a back corner of 
the kitchen counter, then plant it in the fall. Probably the maximum 
temperature during storage is 80 F. I haven't tried soaking the seeds as 
Diana did, but I'll try it the next time on some of the large seeds such as 
Tropaeolum.
