The Lilium gloriosoides pollen which Siggi used was from Dick Cheung. The seeds I got, looked perfect dead, but one germinated some weeks ago.
Dick did not reply when I emailed him last year.
Dick had superb lilies this year again. But his gloriosoides seems not to have bloomed this year.
What I read about a upright growing Lilium henryi (until the rain) from brianw, sounds not very promising. Many Lilium henryi you can buy nowadays seem not to be pure. I had some this year from Holland. These looked in all respects like pure ones.
Not upright, but the seed capsule gave it away. At least some are hybrids. Wrong form of seed capsule and at least one had not the right form, size and colour of seeds. Probably some rosthornii or a similar form in it. Probably a back cross of a Hybrid.
So a lot of seeds for the compost, because I pollinated them crosswise.
