Your Welcome! The most seeds I've got from SPD, was when pollinated by Bear Claws, and the worst was with Lilting Belle. I should see the SPD x BC bloom soon, I can share pictures when they start.
Good Luck, with your seeds. I've had very good germination with the white seeds, and the seedlings have all been strong growers.
I've tried crossing other Siloam daylilies, to see if any others produce white seeds. I've tried 6 other Siloam cultivars, and none of them produced white seeds. I'd love to know if any other cultivars produce white seeds. I like oddities, maybe because I'm one myself.
Thanks for the acorn.
