Aad I did a whole series of tests with and without stratification; this treatment made almost no difference. The best and easiest results were soaking in water for 24hrs and then at 'room' temp (20-25C). The only failure were in seeds keep in a warmer place. They took 4-5 months for good sprouting and all conditions were erratic and spread out. I save space by keeping them in plastic bags (baggies) on wet paper until some sprouting starts.

Others say it is beneficially to stratify for 3 to 7 weeks at 5 degree Celsius in a refrigerator.
