WTG, Libby!
To add to what Maurice mentioned about white seeds with Moonlight Orchid, I have read that - and have read that Siloam Peony Display has white seeds at maturity also - multiple people stated that. One person also mentioned Westbourne Cottonmouth and another mentioned Artistic Pink as having viable white seeds. This was in a post on Facebook in one of the daylily groups, I just went back and searched for it and located it to provide this info here.
