I've harvested some other seeds from promising crosses and I have them soaking in cups, in their mesh bags. I take them out and rinse them off and return them to fresh water each day. As I understand it, it's to remove a protective coating that can slow down or inhibit germination. In a normal season, rain and snow do that job for seeds in the ground. I can never remember exactly how long to do this, but think I'll make it a week. Then they'll go into zippered sandwich bags with some damp vermiculite. Then they'll spend about 6 weeks in the fridge to fool the seeds into thinking it's winter. Then spring. Hopefully some will send out a white root!
I used to use damp paper towels in the plastic bags, but it was sometimes difficult to disengage the fragile root from the paper without breaking it - hence, the vermiculite this year. I always save a few seeds from each cross in case this method goes awry.
I have a dozen or more seedlings from previous years' crossings that look big enough to produce blooms in the spring.
