Uli's suggestion to use pollen from Doug's one plant reminds me of something related. Last year I obtained a great prize: a form of Lilium candidum which evidently grows well under my conditions. When it bloomed this year, I pollinated it with its own pollen and am getting good capsule formation. There is a widespread misconception that lilies are self-incompatible. Some may be. But in an article by David Griffiths written about seventy-five years ago, he recommended pollinating Lilium candidum with its own pollen to get seed for commercial production.
