Lee makes a good point about the *initial* climate regime Mediterranean bulb seeds may endure. In accordance with this principle, I usually let spring-harvested seeds sit around a few months before refrigeration. Once in the ice box they stay there until planting time, which can be 10+ years. N.b.: While viability is reduced over any longer period of time, even a low percentage germination rate can be adequate. A few sprouts out of 100 seeds sown of Lachenalia pusilla over 10 years old is gratifying. Mauro's challenge may be common in more humid climates. However, I have always noticed that a household refrigerator tends to have a desiccating effect: try leaving unbagged cilantro in there for a day or two. Dylan
