Tina - Thanks! I will try that. I wondered if storing the pollen in the refrigerator instead of the freezer might work better. You answered my question for short-term pollen storing.
Sue - I don't know. I didn't dissect the bloom.
Michele - That's a good idea! I typically tag mine when I pollinate them because I don't have as many. This year I only have 2 seed pods from older daylilies that were open-pollinated. I wasn't planning to hand-pollinate any of those, but apparently a bee or butterfly did!
Today the final bloom on that daylily opened and it does have a pistil, so will try once again to hand-pollinate it. If the frozen pollen is any good at all. (sigh)
