    At least a year plus...mine seem to be sprouting even well after a year.

    When I first started procuring seeds, particularly sundew, I mixed sand and peat and placed the slightly moist media in plastic pipette containers, that have a hinged lid. I had the containers by eastern window sills, to avoid greenhouse effect and usually by 3 weeks I would get germination. A lot of sundews also need to be at least 70 F. Sometimes the seeds you receive are just infertile, and no matter what you do, they fail.

    Got my seeds today. Am delighted that the ICPS labels the seeds that need cold stratification and tells you on some where the seed came from.

    Will try at least two methods IF I can divide the seed packets in half easily.

    I now have 11 drosera species started in just distilled water and the same 11 in a mix of peat and perlite.

    How long do these usually take to germinate?

    Also, how do I cold stratify drosera seed? I've read about the sarracenia but haven 't seen anything specific to drosera.

    Depends on the seeds as well as the species. Any where from 10 days to two years.

    Cold stratification is pretty much the same as for Sarracenia, the major difference is the size of the seeds. Stratify them in finely chopped live Sphagnum or LFS, moisten with most of the water squeezed out. Or in the pots themselves. Or a damp paper towel with most of the water pressed out. Seal them in a plastic bag making sure there is plenty of air and pop them into the refrigerator for at least 4 weeks.

    Note that not all temperate Drosera seeds need cold stratification. Be sure to check each species and form/variety/location.
    Grand Hotel... always the same. People come, people go. Nothing ever happens.
