Yes I have tried with the dip pollen. I also saw a suggestion on here awhile back about flowers that have no stigmatic fluid to take fluid from another very fertile plant and transfer to the stigma of the flower that won't set pods. I tried that last summer and actually did set a couple of pods on an older daylily Boagie, that has never set pods for me. So I know that method can work. I guess some plants don't produce the fluid necessary for pollination. Startle is one that I have not been able to set pods on. I have heard it is nocturnal and to try at night. May try that and see what happens. I love to experiment and see what works best.
