If I got my information right filiformis need two month stratification, right?

Two months should be fine.
Filiformis have such a wide range that some see a one month Winter and the other end of their range see a three month Winter.
But a 2 month cold damp stratification period should work for all of them.
Just my 02¢ worth.

At least for the few different Florida filiformis I needed zero stratification but resulted in a low germination rate.

I wonder if the same is true for your variety

Temperate varieties need the stratification unless very, very fresh. Even then you'll have a very low germination rate without it, like 1%.
On the other hand, the subtropical varieties do not require stratification, and you will get decent germination without it. However, since they're still genetically wired for stratification, you'll usually get a better germination rate with stratifying the subtropical ones too.

Very interesting. I'm getting even more curious about these plants by the day. It makes plenty of sense really.

Though I'm extremely curious why a plant may still choose to grow without stratification, perhaps because they aren't quite as precise as a computer. You know me, manipulation of nature is what makes it interesting!

Although if your "1%"is accurate. That amount of germination without stratification would damn near be a fluke. Very perplexing plants.

My 2¢ worth: A few years ago, I bought 4 Florida Red plants from a seller near Orlando. They bloomed like crazy, and their seeds needed no cold stratification. By the end of summer, that plant tray was full of little red threadleaf sundews. If you're sowing seeds from plants in North Carolina, New Jersey, or New England, then those need cold stratification.
