Germinating Pulsatilla occidentalis

[Catwheazle]

Hello, does anyone here in the group have Pulsatilla occidentalis in cultivation?
I tried Jelitto seeds under various conditions, but no germination.

Addendum: Sorry, I made a typo 🙁 I meant Pulsatilla occidentalis, not nuttalliana.

If things are so bad, it is worth a try with some seed using a soak in saltpetre (potasium nitrate).

Unfortunately, finding a (as in singular) "recipe" online is impossible as recommendations online vary a great deal in concentration of the saltpetre and soak time.

If you have seed, try 1% and 6-12 hours.

Whatever you try, it always assumes that seed is viable, and I am very far from convinced that that is always so.

Unfortunately, I don't have any seeds, and I'm afraid the ones I did have were already in storage. I'll give it another week, and then put it back in the fridge for another six weeks. Maybe that will help with these cold-germinating seeds.

I have been a passionate seed-sower for over 40 years.
Some seeds survive storage by humans, some do not.
Even in dry habitats, seed will fall and not desicate to the extent of storage by us humans and remain viable for numerous years.

Iridacae are a great example - sown fresh most/many will germinate like cress. Store them for any length of time and germination falls away. Let the seeds fall and get incorporated into the soil and seedlings may appear 10 years later.

OK, thanks for the info....
