Drosera filiformis var. filiformis germination?

I'm receiving some seeds of Drosera filiformis var. filiformis, and it says on the ICPS's website that they need to be stratified before they germinate. Should I stratify them in the fridge when I get my seeds in a few weeks, only to have them face natural winter a couple months later, or should I just wait to stratify them during natural winter? Do these seeds do best when sown immediately like dionaea, or will the germination rate continue to be high after several months?

I have had 100% germination rate with MANY species of temperate drosera ALL without the recommended stratification. D. Binata, D. Filiformis, D. Intermedia, and D. Rotundifolia. I guess it may be random luck, but so far i have skipped stratifying the seeds and i have had crazy germination success. I just sowed s bunch last week and theyve already started too. It may be luck of the draw, but its worked for me.

I personally don't consider D. Binata a tropical, it will go dormant right alongside the rest of 'em if it wants too. I'm pretty sure it's basically a temperate that can behave like a tropical if treated like one.

You're both right. See here:

Some populations go dormant in the winter, while others are truly tropical.

And back to the original post, I would recommend the old fashioned cold startification [fridge] for at least 6 weeks.

Thanks everyone for your answers, I think I'll stratify half, and just sow half, and I'll see which one has a better germination rate.

Good idea man, that way you figure out what works best for you! Good luck!
