Essentially, the seed is sown on a top layer of sand, placed in tray watering, but the surface is misted daily. Presumably, this leaches out the inhibitory enzymes thaat are in the seed coat which are very stubborn in seed that is not fresh.
I am pleased to have germinated Polypomphlox, Pink Petticoats, or U. multifada. I miss the old genus name :-( This is a nice rosetted plant, and really quite different to my way of thinking than Utricularia. It reminds me of Genlisea in a superficial way.
Only a few seeds so far have germinated, and this is an annual species so pollination is necessary to obtain seed.
Dodec, have you had any results pollinating your flowers? See, I'm worried about it already!
