I had an old blue Iris and some hbrid Daylilies produce seeds summer of 2008. Neither will come true from seeds but for for the fun of it, I planted the seeds in October in my coldframe. These seeds are hardcoated and need stratification (cold treatment) to break dormancy. The freezer is chancey because it is the same temperature. What these seeds need is alternate low and high temperatue that Nature provides.

The seeds I planted in the coldframe will sprout when the temperature is right for them in the spring. I have started tree seeds the same, along with hardy perennials with high germination rate. Right now my coldframe is full of seeds sown in October. The only cover is wire to keep animals out. The seeds have gone through rain, snow, below freezing WY weather. It will not kill the seeds.
