sundewmatt Posted October 18, 2016 Report Share Posted October 18, 2016 (edited) A month ago, I planted a ton of Drosera seed that had been stored in the fridge for over 10 years. The germination rate so far has been surprisingly good. I also planted 1 Sarracenia, 1 Heliamphora, 1 Darlingtonia. Seed was planted in warm conditions (no stratification) and so far, there has been no germination. And finally, I planted 4 species of SE USA Pinguicula. So far, there's only a single P. planifolia seedling. Does anyone know if ancient seed of the above non-Drosera varieties ever survives? Finally, I just discovered another batch of seed that was stored at room temperature for around 10 years :/ I'd be curious to know if anyone has had good results from seed stored under such conditions. I'll still plant a ton of it and try to post my results, but it would be nice to know what to expect so I don't check all my seed pots as obsessively as I've been checking the current batch! I'm particularly curious about Sarracenia and wonder how old is too old... Edited October 18, 2016 by sundewmatt Quote Link to comment Share on other sites More sharing options...
ada Posted October 18, 2016 Report Share Posted October 18, 2016 i've had sarracenia seed germinate very well after 6 years being stored cool and dry. It was however stratified as normal from december in a cold damp greenhouse. Quote Link to comment Share on other sites More sharing options...
sundewmatt Posted October 19, 2016 Author Report Share Posted October 19, 2016 Thanks Ada. That gives me hope for this purpurea x flava seed I planted that was stored in the fridge for a long time. So then there were cold temperatures for 3 months or so then? Have you tried any older seed? Quote Link to comment Share on other sites More sharing options...
starseeker Posted October 19, 2016 Report Share Posted October 19, 2016 If i remember correctly ,there was some grain which was found in one of the great pyramids which the scientist managed to germinates,so in the scheme of things seeds at ten years old are mere youngsters !:) 1 Quote Link to comment Share on other sites More sharing options...
