    Has anyone heard of putting the seeds in paper towel or a thin layer of water and freezing/ thawing out occasionally for stratification? Someone(you likely know who you are and this is an invitation to discuss this method) mentioned them when sending some S. purpurea seeds with locality data over to me. Since things are starting to warm up here I've popped them in the fridge with peat and sand(will take a photo and see what you guys think).

    Sarracenia leucophylla(seedling)

    S. purpurea and Drosera filiformis filiformis/ intermedia seeds waiting to sprout.

    JBL turns them into seedsickles. Aside from that, ya figure that in nature, with the ebb and flow of frontal sytems, they must expereince some amount of freezing and thawing.

    Doing that wouldn't give you any advantage over just keeping them at 4C in the fridge for 5 weeks.

    Maybe not Alexis, but I get very high germination with just 2-3 weeks in freezer. But I have not tried a controlled experiment. Maybe I'd get the same results in the fridge. Good experiment idea! Maybe Jimscott is game? Or is this not funky enough for him? [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_m_32.gif[/img]

    Definitely something I would try! I am doing a modified Bugweed approach. I have seed species in individual bags of water, in our attic. It isn't freezing, but it's cold. I'm about to open the bags and spread them across media, now that it has been 3 months.

    People have been trying to speed up stratification with quick freezing for years. Seems a lot of messing about for no gain to me [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_n_32.gif[/img]

    SO! Modifying my Bugweed, eh? OK! Tell me how it works!
    Allan Lowrie in Australia sez, you can put them in damp paper towels and put them in the freezer for 48 hours and that will do it. Says a 40% germination rate. Not me. I will stick to tried and true methods and keep going for 95% germination. Only 85% germination so far.

    I've used the paper towel method with excelent results! In Fact, I have developed the following web page to illustrate my method:
