I've noticed that capillaris seem to be more needy of heat to get germination, moreso than other sundew species. I've germinated quite a few different Drosera at room temp, but not capis. They have all consistently needed temps about 75-80°F to sprout for me.
My capi seeds live at about 78 under my lights, so if it is
heat, probably low-mid 80s might be a better starting point. My guess is it's the heat and humidity combo. On the other hand, I typically have little difficulty germinating Emerald's Envy and Eatonville, both of which are originally from the Florida panhandle. It may be that each successive generation of "domesticated" seeds are simply better suited to live in typical household conditions, having descended from plants that managed to mature maybe at one edge of their native comfort zones.

Interesting, that the fresh seeds aren't doing that good. How about in comparison with the older seeds I sent you...better, worse, or about the same? Maybe they need a longer drying period?
I'm not noticing a big difference. The old batch produced just one seedling, the fresh batch maybe 5. Too small a sample to draw any conclusions, I think. Currently the oldest, single, seedling is showing signs of stress - the leaves are semi-dry. I don't know the cause, it may merely be a late watering. I'm hoping it'll recover ok. The other seedlings are still tiny, at the stage whether they're either ok or not there.
Every morning, I take my cow on a long walk through the local vineyard. Yes, I herd it through the grapevine.
